I am observing something that is very counter-intuitive to me: I/Q
modulation is very susceptible to phase noise?
In an experiment I plot "phase noise" vs. "SNR" and see a constant slope

Can anyone give introduction about POTSBAND Design filter? and what the purpose of this filter???
I found matlab code for this filter,
function [b,a]=bandfilter(fs, f1, f2)
%POTSBAND Design ...

This has probably been answered already but how does one the 'DFT' samples
of an IIR filter from the 'b' and 'a' coefficients.
For a FIR, this is trivial.
if b_n are the coefficients which are...

I want to know the physical significance of liftering process.
with Ci as ith feature element in the feature vector, the liftering
changes Ci as
Ci = (1 + (N/2)sin((pi*n)/N))*Ci
What is it ...

I'm looking for known algorithms that do envelope/peak following with no
user-specified attack or release times.
Specifically I'm interested in what kind of algorithms something like:

I have and interesting design that involves designing two filters that are
very related. (I call them companion not to confuse the word with

I was studying the schematic of a 1970's era washing machine sized disk
drive  wondering how it performed ECC. Everything was built out of
simple SSI TTL circuitry.
The disk controller had a 1...

I am struggling to manually apply the scale values to a digital filter I
designed in MATLAB using fdatool.
I generated the filter (IIR band stop filter consisting of four second
