## removing noise from an Audio file in matlab using notch filter using (1 - exp...)

hello everyone , i need help please , i need to write a matlab code that reads an audio file and removes the noise at frequency of 1000 hz. the noise must be also added manualy in matlab code. after that filter it. the frequency response can be designed in the form (1 - exp...)(1 - exp...), where the complex (...)

## Signal power in Matlab

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

## Applying WAV, MP3, analog music to MATLAB & bandpass fil

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 (...)

## how can i use matlab to simulate this kind of filter?

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

## speech noise reduction in matlab

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 (...)

## complex FIR filter and SSB signal

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 (...)

## single sideband bandpass signal & complex FIR representa

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 (...)

## design FIR Filter in HDL-how to map graph to hardware design

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.

## How to implement filters on FPGA?

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 (...)
