Hi, I m really new to DSP so dont be hard on me. 
Ok to explain this simply as possible, I have the same signal in two data paths,
one flows through a Chebyshev type 2 low pass filter at some cut off frequency
f0, and the other path having a butterworth low pass filter at cut off frequency
f1. I need to compensate for the group delays induced in the signal on each
paths before any comparative signal processing. How do I do this compensation
thing? I have to implement it in C so please bear that in mind.

Regards,
Safi
