Returns the phase delay ${\tau }_{\varphi }(\omega )$ 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 ${\tau }_{\varphi }(\omega )$.

Examples¶
