sdr.FIR.frequency_response(sample_rate: float = 1.0, N: int = 1024) → tuple[NDArray, NDArray]

Returns the frequency response H(ω) of the FIR filter.

Parameters:
sample_rate: float = 1.0

The sample rate fs of the filter in samples/s.

N: int = 1024

The number of samples in the frequency response.

Returns:

  • The frequencies f from −fs/2 to fs/2 in Hz.

  • The frequency response of the FIR filter H(ω).
