Why does the frequency sampling method for FIR filter design operate in this manner?

Thanks to all for your help! Here's what I understand, please correct me if I'm wrong When performing a time sampling using $T$ as the sampling step, it produces a frequency periodicization with $1/T=...

Why does the frequency sampling method for FIR filter design operate in this manner?

This answer shows one way of understanding why and how frequency sampling works. Let's assume you're given a desired complex frequency response $H(\omega)$ on the interval $\omega\in[0,\pi]$, where $\...

Why does the frequency sampling method for FIR filter design operate in this manner?

Interesting to see the links and history from Dan and Robert and reference to Matt's thesis and derivation for FDLS, which I hadn't viewed previously. This is similar to approaches we've used since ...

Why does the frequency sampling method for FIR filter design operate in this manner?

Explanation: The impulse response and frequency response of a filter are Fourier Transform pairs. The time domain response of a filter is its impulse response: you put an impulse at the input of the ...

Why does the frequency sampling method for FIR filter design operate in this manner?

This is how I would define the frequency-sampling method. Assuming linear phase (to start with). Draw out your desired frequency response magnitude, with as much detail as you need to to define the ...
