An IIR filter implementation suffers from instability and zero-input limit cycles when the poles are located near the unit circle. Recently, I developed an optimal...

Hi, in this thread, @rbj mentioned that the MathJax implementation in this forum is erratic and I believe him. I had issued in the past and it is always frustrating. ...

I have made an impulse response of an acoustical system.  I have windowed this impulse response to filter any reflections.  The window length used on this impulse...

I am having difficulties accepting the validity of FFT interpolation / time domain zero padding. When a section of time data of length T is selected from which...

Hi,I have a signal coming from an ADC that I oversample with an fs=80kHz and then I subsequently average 8 samples to get a rate of 10ks/s. I feed this averaged...

DSP Gurus:I am looking for some direction. I am working on a FMCW radar project. I have the IQ mixer sampling, zero padding, windowing and FFT all working. My problem...

Hi ,            Consider two complex numbers  Z1 and Z2 and the following definition of  magnitude difference |z1| - |z2| --------- (1)   First compute...

Hello,I have published an article on Matlab on common mistakes in subband adaptive filtering. https://www.mathworks.com/matlabcentral/fileexchange/72169-adaptive-filtering-in-subbands-common-mistakes-workarounds...

Hi all, I am doing a study in which I want to compare some different methods for signal generation and also detection.  I am trying to achieve the following:1....

Hello all,   It's my first participation here. Greetings ! I'm having an FIR filter with 1024 taps which represents a channel. I would like to find and equivalent...
