Re: How to efficiently control an FIR's magnitude response by altering its phase spectrum

Thanks! Yes, that wonderful book taught me a lot about signal processing years ago.Steven (the author) touches on the topic I'm interested in:Now consider this:...

Re: How to efficiently control an FIR's magnitude response by altering its phase spectrum

Sorry for the late reply and thank you for the script. Among other things, the animation nicely showcases what I was trying to point out by the graphics in my...

Re: How to efficiently control an FIR's magnitude response by altering its phase spectrum

Hi Fred, thanks for the book suggestion. I will check that out.I am unfortunately not sure I understand the method you are describing. You used a quadratic phase...

Re: How to efficiently control an FIR's magnitude response by altering its phase spectrum

Hi wolf22, I think you mostly understood my question, though not 100% correctly.I want to calculate a FIR filter, whose frequency response I want to exactly define...

Re: How to efficiently control an FIR's magnitude response by altering its phase spectrum

The ifft approach is not blind to phase. :) If you multiply “Amp” in your code with some random complex numbers that have an absolute value of 1 so that they...

Re: How to efficiently control an FIR's magnitude response by altering its phase spectrum

Hi kaz! Thanks for your reply. You are correct. I want to gain as much freedom as possible over the amplitude response for a given filter length while not caring...

How to efficiently control an FIR's magnitude response by altering its phase spectrum

Note: I posted this question on Signal Processing Stack Exchange yesterday. Because the one answer I got so far was not-so-satisfying, although surely well-intentioned,...
