the frequency response can be designed in the form (1 - exp...)(1 - exp...), where the complex exponentials have to be designed to be 1 at f0 and ??f0 respectively.This shows a transfer function of cascaded differentiator. please help me with this, thi
hi all I'm using the functions(fft,ifft) in a matlab code,theoretically signal power must not be changed before and after transformation according to Parsaval theorem. But when calculating the signal power before and after using E{X^2},the power of the 2 signals aren't the same. please can any body helping solving this issue. Thanks
I am trying to separate music from MP3s or WAV or just the analog output, into 4 separate channels or frequency ranges. How do I actually apply the music to matlab for filtering, and if I am using fdatool, can I do 4 bandpass filters, I only see two? How? Am I going about this the wrong way?? This is for senior project. My goal is to (...)
sorry maybe this question is stupid but please teach me~~~ i studied microwave filter from textbook and now i designed a BPF by ADS shown below~~ the result is good and right~~but i want to use the matlab to simulate it~~~ my question is here the port 1 is 50 ohm, and the port 2 is NOT 50 ohm~~~ i can solve the circuit with both ports are
Hello! I'm working on a thesis about Speech noise reduction in matlab. Basicly these are the steps Im following: 1.Read oiriginal signal 2.Add Gausian noise 3.Frame sampling 4.complex Spectogram 5.Magnitude filtering (Using a bilateral filter) 6.Reconstruction(IFFT,Overlap resynthesized frames,Normalized (...)
Dear friends, As a part of my thesis which is to design a bandpass sampling receiver I have two basic questions to ask: 1- How to express and show a single sideband bandpass signal in matlab. 2- I have the transfer function of a complex FIR filter and the coefficients but I don't know how to express it in matlab and (...)

If you have never done filter coding in hardware I suggest you try matlab/Simulink with HDL coder along with System Generator(Xilinx). You'll be designing and synthesizing complex filters in a couple of days.
Hi, It all depends!!! One way as our friends mentioned before, you can use matlab (with SystemGenerator by Xilinx, DSPTool by Altera) to generate simple to complex DSP algorithms (including filters). Another way is to use a DSP filter core provided with the vendor design tool (i.e. ISE, Quartus II, etc.). These (...)
The output from "add" block is a real plus imaginary signal,but the Power Amplifier requires complex input and output a complex signal as well.The Bandpass filter requires a real input.Anyone knows the way to change from "double to
I want to use matlab to general the test bench code or some complex signal wave file, the simulator, for example, altera's quartusii or xilinx's ise(in fact modelsim) then use the wave file to simulate. The simulation result can be send to matlab to view the wave or the frequency spectrum. when design a digital filter (...)
