alz help me in doing this problem.............. "Make an m-file to low pass filter a signal x(t) consisting of two cosines at 5 and 20 rad/s using an RC lpf. Choose suitable values of R and C to allow the cosine at 5 rad/s to pass through and suppress (filter out) the cosine at 20 rad/s. Plot the spectrum of the input and output signals, as we
I am trying to design a low pass filter using butter filter in matlab I am confussed how to od this. If my carrier Fc is 20000,( but can be changed if needed) and Fs is 44100 (MP3 file) what do I put in the matlab function below? Please help me I can not get htis please?? I need to filter: outfm = Ac * cos(wc.*t + 2 * pi * kf * cumsum(snd)); Fc
Hi, Iam trying to do some analysis for a redar system that uses Linear Chirp modulation. I have a problem mixing the Tx and Rx signal then lpf. RX is a delayed version of the Tx. Normally after mixing (muliplying Tx and Rx) i dont get the low freq part!!! I tried matlab Help but i cannot get it! Any help Please? Ho
for example in a communications system the the signal band may only be narrow, KHz wide, but the signal band could be centered at RF frequencies, at many MHz. If the signal is sampled according to the Nyquist criterea, i.e. twice the highest frequency, then the data rate for the RF signal will be very high. Processing the data at this high rate is
I designed a circuit to detect the ecg signal. I applied it to pc through the mic. input, then i applied it to matlab using the wavrecord function. I can select my sampling rate and the number of samples to record. Now,first i want to plot the signal against time. Can this be acheived by just the plot command, or i need to create a time vector.
I wish to implement a discrete High-Pass-Filter (HPF) in matlab/Simulink. I found a discrete Low-Pass-Filter (lpf) in one of the Simulink examples as z Denominator: z-exp(-2*pi*fc*Tsc) fc: cut-off frequency Tsc: sampling period Could some

how can I use matlab to send and receive digital data through parallel port
Hi How to use matlab write a Low_pass filter .. I can use simulink for simulation , but I want to know how to write a matlab code.. simulink file can novert to matlab code or not ?? a low pass filter = 1/ (s+1) = e^(-t) but how to descript expt(-t) in matlab code ?? thank you
Firstly, I am a newbie to use matlab. So I have some problems to ask you: 1, If I want to simulate the PLL's behavior model, is the simulink in matlab proper? If not, what 's it? 2, How do I build the behavior model to obtain the behavior model that is close to the actual situations? 3, Where can I get some useful articles to introduce related

I'm simulating a QPSK receiver in matlab. How can I use extrenal data file to use as a data input to my receiver?
Hi I see in matlab 7 very long initialization time, up to 1 minute. I have toolbox cache enabled. In version 6.5.1 this time is about 2-3 secconds for my computer, also with toolbox cache enabled. Messages after caching are almous the same: Toolbox Path Cache read in 0.16 seconds. matlab Path initialized in 0.28 seconds. for both versions
I'm dealing with the curve-fitting using the function--nlinfit in matlab. Here is the syntax : beta = nlinfit(X,y,'model',beta0), and I don't know how to define the term 'model'. Can you give me some advice,thanks.
hi hi, i'm a beginner in matlab and have been having problems regarding the "ss2tf" function. i type in: A= B= C=eye(2) D=zeros(2,1) find ss2tf and it gives me: ans: 1 2 3 4 5 instead of: NUM= 2 2 DEN= 4 which i'm expecting as the ans. can anyone out there help me?
Hi, I am dealing with a digital resonator filter in matlab. The transfer function is K (z^2 / (z-p1)(z-p1*) ) where K is the gain. It is simplified to K / (1 - 2 r cos 2pi f0 z^-1 + r^2 z^-2) Given that samplig rate = 128kHz, resonant peak at f0 = 48kHz and 3dB bandwidth is 4kHz with unity gain at its resonant peak. I was asked to plot the

Hi everyone, I'm currently writing a matlab problem that has one of this command line x^4+c3*x^3+c2*x^2+c1*x+c0=0. My aim is to come up with the values of x. All the c3,c2,c1,c0 parameters have been properly defined. However it keeps showing the Error File that the assignment statements cannot produce a result. Could I ask why is this so?

I simulated my signal using FFT (Blackmanharris window) in matlab which gives me 16-bit reolution (96dB) but when i import the same signal to using sam FFT window in SPICE, the result only became 80dB left. Can any one answer why this happens and how should I avoid this problem. Thank you very much!
I think it is the voice band, 0 to 4khz. sampling rate 8khz ok! but what is that 40 ms duration? one more doubt i have.. u say sampling rate is 8khz, it is the sapling rate of the wave file. then, for it to be effectively reconstructed, the largest frequency must be < Fs/2 = 4khz. then u are applying a lpf from 0 to 4k

hi, pretty easy code. there are functions in matlab. the "find" function along with "max" and "min" can be employed to get what u desire for. even find is not necessary unless u want to get the index of those values.. suppose ur matrix is a = magic(5); then max(a) will list out 5 values, with each value the max of the columns of "a". c
