hello, i want to ask about how to implement clock sampling error using matlab i tried to use resample but it dosen't suit my requirements
hi.... i want to remve noise from an raw eeg signal using matlab...can anyone provide the matlab code for the same?????/ plzzzzzzzzzz
How to segment the ECG signal using matlab
Hello. i want to create an rfid signal of 125khz. that i am planing to add some noise so i can do some processing on it on future work. if any one can help me on this or give me some clues to get started i will appreciated that. regards.
kirjmaru, Do you try Gibbs sampling, yet ?
hi for all how can I generate (1)Digital optical signal (2)PCM (3)analog signal using matlab plz quick
HELLO i want to interface an microcontroller with the PC and process the received signal using matlab,,,i may use PIC 16F877,,,,,please if anyone can give me a tutorial about that or describe to me how to do so in some details it would be great,,,i want to know how the signal interface to the serial or parallel ports ,or (...)
Hi all, I have a signal vector... i would like to add some random noise, or some arbitrary peaks somewhere on the signal, or change the weight distribution of it (for example shifting the weight more on the right part or on the left part)... etc. How can i do such modifications on my signal using (...)
how to get frequency spectrum of EEG signal using matlab?abs(fft(x)) is not giving good plot
hi, you may have to evaluate the function h(t) at your sampling intervals and then use it. Thus the length of the filter will vary. This is assuming you are using sampled data. If you want analog response, you should use symbolic toolbox.(or something like that) brm
I have some problem about Multirate signal Processing.(by using matlab) 1.) Design a standard sample rate converter to convert the signal x at sampling rate 8 kHz to y at sampling rate 22 kHz. Put the interpolator first and decimator later. Combine the anti-aliasing filter with the post (...)
hello there!!! :cry: I really need a help on how to reconstruct an ECG signal from the binary data using matlab... The binary data was originally being converted from the real signal of ECG by using the microcontroller. Basically, my project is about Bluetooth ECG System...Hope, there is someone who could (...)
Hello there!!! Can anyone help me on how can matlab reconstruct the ECG signal?The data sent via serial port n it is in digital format that is in binary form(the real signal is in analog and has been converted into digital by microcontroller; PIC168F)... I really stuck on this...I have make some research regarding to this matter ... (...)
Hi all, Can someone help me to prove this question without using matlab. I have found the sampled signal x to be x= since 8 samples in 1 secs. Qn1) since the sampled signal is x= we can actually show that the reconstructed signal of 2 sine waves by pur
dear explorer, I measured (sampled) a weak signal with 100 msps 14 bit Gage A/D converter card. then I give the FFT of the signal and find two important frequency band of possibly wanted signal. how I can reconstruct time domain signal using digital mixing at specific frequency band (with (...)
hi,all Can anyone provide for the Instructors Solution Manual of "Digital signal Processing using matlab" by Vinay K. Ingle, John G. Proakis. Thanks.

Hi, I need the book in pdf format. "Digital signal Processing using matlab" By " John G Proakis" and " Vinay K Ingle" I also see the previous posts about that book but no one open this book. plz if anyone have this book then gave me soon in pdf format. THANX.
I am trying to calculate the cross-spectral density for a voltage signal using matlab. I am using the fft function to do the Fourier transform. The fft function is Y=fft(X,n). But I donot know how to pick the points n. My voltage signal Y is 2seconds long. dt is 0.0001s. so sampling (...)
hello plz i nedd this book as soos as possible "Algorithm Collections for Digital signal Processing Applications using matlab" by E.Gobi thanks alot
CAN ANY ONE GIVE RELATED EBOOK FOR THIS TWO TOPICS UNDER DSP PLEASE
Its easy. u should know the sampling rate of the signal. Then you can create a frequency vector like F=linspace(0,1,number of data points/2)*Nyqusit_limit . So find the index of the point in your FT with maximum value( which is your highest frequency) and look the value of F with the same index. So at last u will get the frequency value.
HELLO, my project's name is "design and imagery sampling with Automatic Gain controller(AGC),using matlab." Who can help me,
U can use sppech proessing S/w , It is basially demodulation using different sampling rates.
please tell me any free ebook available on matlab with emphasis on DSP
Help! How to get the transfunction expression if I give the small signal equivalent circuit in matlab? Thanks.
hi, In fact I don't exactly understand what do you want to say, but what I know is that you can modulate your signal by every signal youy want with the condition that your frequency must be greater than the frequency of sampling you used
hi all; could you please introduce me any book in fdtd & fdfd using matlab. thx alot.
hi iam engineering fianl year student please help me in my project i want to generate upchirp and down chirp signal in matlab without using inbuilt matlab function "chirp" i want to write the code to do that can anyone help me please..
Hi! I have a question on matlab as follows: The signal x(t) = sin(ω1t) , given ω1 = 5 , is sampled at 7 samples/sec during8 sec. Compute the power spectrum for the sampled signal. Can any body help me with that? thanks
I want to analyse the chirp signal using matlab. I tried to use FFt but i couldn i dont want to use the toolbox. i want to write a code! any help please
Hi, I have to realize for my final project a simulation of a radar system using matlab. The theme is: "The project consists in the implementation of a complete radar signal processor. One data file with an unknown target distribution is included as a mystery signal for testing. The objective of this project is to devise a (...)
I need to create these two signals: 1. Non-stationary signal : for STFT analyzing and Wavelet analyzing. 2. Non-Gaussian signal: for Double-spectrum estimation. I've done some simulations using matlab, but with no satisfied results. Maybe it's because of the source signals.. Could (...)
hi all: i want to test the sfdr at Nyquist sample using matlab, the programmes i have all use oversample ,can anyone give me some message on the difference between the two or some programme material on Nyquist sample? thanks in advance!
i had try this using matlab. i use pulse generator to generate the wave. but there is some warning. Can someone help me to find the
i really need solution of dsp using matlab proakis. can anybody sent me? thank you
Be clear that in matlab you can do only FFT which is a efficient form of DTFT. now lets take a analog signal x(n)= A sin (2*pi*f*t); ( in a PC nothing is analog)... so lets make it Discrete ... and the sampling freq fs = ( 1/Ts) lets and fs > 2*fm .. fm = max freq in our input signal lets take Ts=0.1 (...)
I want books related to DSP using matlab if anybody knows can send links plz!!!!!

I am a begninner to learn DSP. Do you guys have any good resource or material which I could read for this topic. Especially, the material by using matlab is my weakness. I want to learn more about how to use matlab to analysis the DSP. Thank you!
Hi friends, I am trying to display time domain signal in Frequency domain using matlab.I took frequency of signal as 100hz and sampling frequency as 1000sampels/sec I have tried using 'fft' function but not getting. Anyone of you give me the solution for displaying frequency (...)
Hi, Can anyone tell me how to plot this fn using matlab Tb sinc^2(fTb)sin^2(pi.f.Tb)
"sampling rate= length(yy)/10" What is yy? Whatever yy equals, that equation doesn't seem right. Sample rate is usually a constant, dependent on the instrument's A/D converter design, not the length of some array.
while iam taking Line in for record voice by using matlab ,it wont separate, its give as one channel Anybody can explain why it so that?? Thank You in advance NNM
how do i write codes for bandpass filter using matlab wb = sin(2*pi*3500*t); wc = sin(2*pi*8000*t); tx = wb.*wc;
Hi, everybody. I am using matlab toolbox "delsig" to do the system design of a second order ADC. In the "delsig" toolbox, function " realizeNTF ( ntf, form, stf ) " can set the coefficients for a particular modulator topology. It works perfectly with default input "stf=1", but when I set the stf has the same poles as ntf, matlab gives me (...)
