RF-Chain Signal Delay for Sensor Switching
Lets have a RF-chain as above with system bandwith from HP corner to the green line say 1 MHz.
The signal accumulates delay as it passes through this analog chain, and due to it being non-liner filter ...

Group Delay of Mulitrate system
how do I find the group delay of multirate system.(sample rate converter) , IIR non-linear phase filter
Say decimation by 2 (with lpf) = tf1(num,den)
then again decimation by 2 (with lpf) = tf2(num,...

A Delay Between Two Filtered Chaotic Signals
it is a common practice to use a shift of cross-correlation peak to evaluate a group time delay of two signals (chaotic signals are included). Can one synchronously and equally filter these chaotic ...

Spectral analysis of a cross correlation function [duplicate]
So it's widely known that the Cross Correlation of 2 signals helps us in figuring out the time delay in those signals by analyzing the peak of the correlation coefficient in the time domain.
For ...

Delays and alignment issues: how to compute the an equalizer delay?
For example, if an equalizer model experiences a delay due to its processing, the equalizer may misinterpret the boundaries between the equalized symbols it outputs and, therefore, return meaningless ...
