Dear, i will be grateful if anyone can send me the matlab code for using Method of Moment technique to find out s11, directivity and gain of dipole antenna. Thanx
Dea Forum Im designing a FIR filter, in this case a low pass. I get the coefficients from matlab (no matter from where..) ,that are from 0 to 1, in floating point. Now, I want to implement this FIR in my FPGA ,with buil in 18x18 multiplier. So,I transform the coefficient in integer value of max 17 bit (1 bit for sign) ,multipling the big
: 157251 157250 how do I plot the Phase margin and Gain of PLL? i'm trying to do an ac simulation but got confused what to put at the inputs and what s
I did simulate a microstrip line in a EM solver, and extracted the distributed circuit parameters in a matlab script. With these parameters, I can build a circuit in ADS to which has comparable S-parameters with the EM solver simulation. This gives my linear circuit parameters. Further, I introduced some dielectric materials onto the microstrip
Hi I would like to display the BER of Ultra wideband transceiver. Taking account that i designed this transceiver in ADS then i extract its output signal with the extension .csv. I put this output file.csv in the same location of file.m then i would like to calculate its BER. I'm so gratefull if you can give me a clear tutorial to display BER;
A = b = .' size(A)=5x5 rank(A)=3 det(A)=0 So A*x = b does not have unique solution. Solution x is x = d + t1*c1 + t2*c2. Here d = .' c1 = .' c2 = [
For biometric lock take a look:
I was referring to link that describes the generation of sine through LUT exploiting quarter wave symmetry. I wanted to understand the concept and also how it is different from Cordic?. matlab always recommends LUT based sine/cos over cordic for fixed point implementation. Why is so?
Hi, I'm designing a wireless transmitter that consists of a DAC, a switched-cap baseband filter and a passive upconverter. I'm trying to simulate the spectral performance (ACLR and EVM) and produce constellation plots using QAM signals. The signals have been generated in matlab with RRC pulse shaping or come straight from th
For my research, i need to implement a Turbo Decoder to test a few things. I was able to write the BCJR algorithm code in matlab and for the most part, it works fine. By working fine, i mean that after a number of iterations, the number of errors reduces to zero or flatttens out. Where i am having a problem is that there are times where the number
Please let me know that I want to interface IDEMIA CBM-V3 fingerprint sensor with Arduino. How to read sensor communication system?156362
Hello, I am a student doing research in high-speed electrical link. I have came up with a new signaling scheme, and want to see spectrum plot of it but not sure how to correctly perform fft on the signal in matlab. My signaling scheme, uses phase modulation to have same spectral efficiency as PAM-4 signal (which is 2bits/UI) but has one-UI tha

Please let me know about, 1) Metal Film Capacitor 2) Polypropylene Capacitor 3) Polyester Capacitor 4) Mylar Capacitor. I need picture of Metal Film Capacitor.
certainly like your web site however you have to take a look at the spelling on quite a few of your posts. A number of them are rife with spelling issues and I to find it very troublesome to tell the reality then again I'll definitely come back again.
Hello, im trying to interface my arduino uno with matlab. however, when i try to load my code in IDE software it shows the error "avrdue:ser_open():cant open device '\\.\COM4":the system cannod find the file specified." this in turn results in the connection error in matlab "Failed to open the serial port COM4 to communicate wih the board u
Hi, I want to find cutoff frequency of the two attached circuits. I just want to know is there any quicker way to find it. For the circuit2 I got it as 1/(2*pi*R*C) but I don't see the same in simulation, so I want to verify it with someone. Circuit1:156099 Circuit2:156101 The cutoff frequency
i read a audio signal from my laptop using audioread matlab function, audio signal contains some decimel positive and negative value. is there any way to convert these decimel value into binary bitstream. if it is not possible, then how can i modulate the audio signal like 256-QAM using qammod funtion. please help. if the question is not clear you
Hello, Can anyone help me to know that is it possible to implement any ADC on FPGA board by using Verilog code? Or should i have to go through circuitry, and here i am not talking about implementation of onboard ADC or some external readymade ADC .
Please find the circuit attached. I used the below link for reference but I got an error saying the the block in empty and hence no output could be plotted. I am trying to capture a step response and then use it to calculate transfer function for the same. If any one is able to produce the the frequency response please upload the video or steps.
