Returns the phase delay \(\tau_{\phi}(\omega)\) of the FIR filter.

Parameters:¶

sample_rate: float = 1.0¶

The sample rate \(f_s\) of the filter in samples/s.

N: int = 1024¶

The number of samples in the phase delay.

Returns:¶

• The frequencies \(f\) from \(-f_s/2\) to \(f_s/2\) in Hz.

• The phase delay of the FIR filter \(\tau_{\phi}(\omega)\).
