I would like to ask is there any way to have analytical estimation value of
delay of minimum phase FIR filter based on the following assumptions:
1. we regard the position of largest mag...

I sat down today to get in a little bit of work over the weekend on a
communications project I'm doing for a customer. The channel is not only
highly dispersive, but I'm stuck with a legacy modul...

I have a purely theoretical question.
When doing a FFT of an unwindowed pure sine signal, if the frequency
doesn't match a bin frequency, many bins will have a magnitude > 0.

I am coding a program to do some filtering on an audio file.
So using the method described in Steven Smith's excellent book
"The Scientist and Engineer's Guide to Digital Signal Process...

I always get confused while adding AWGN in my simualtions via AWGN block.
What is the right way to calculate "Input signal power, referenced to 1
ohm (watts)" parameter for different mou...
We all know that Guass probably invented block least-squares, but who invented Recursive Least Squares?

I have a FIR decimation code, which is meant to decimate audio from 44100
Hz to 11025.
My problem is the output is complex, but I need to get this data back to
real number, as the complex
Can you give me your opinion on what
would be the effect on personal computers
(PCs) if their hard disk systems had NO
Would disk storage capacity be reduced?

I have been experimenting with some time-domain pre-processing to
improve the reliability of an FFT application. The application is
extracting the RPM of an engine from the sound it makes. Prior t...

I want to implement Cyclic Q delay, that is used in DVB-T2, in MATLAB
Bits====> 16QAM (for example)====> Cyclic Q delay
say output array of 16QAM is
map_out = [x1+jy1,x2+jy2, x3+jy3,.... xN+j...
