optic.dsp.core.lowPassFIR

lowPassFIR(fc, fs, N, typeF='rect')

Calculate FIR coefficients of a lowpass filter.

Parameters:

• fc (float) – Cutoff frequency.

• fs (float) – Sampling frequency.

• N (int) – Number of filter coefficients.

• typeF (string, optional) – Type of response (‘rect’, ‘gauss’). The default is “rect”.

Returns:

h – Filter coefficients.

Return type:

np.array
