lowpass_filter¶

Synthesize and scale an ideal passive lowpass circuit from a SciPy prototype.

Signature¶

lowpass_filter(filter_type: Literal['butterworth', 'chebyshev', 'elliptic'], order: int, cutoff_hz: float, *, ripple_db: float | None=None, stopband_attenuation_db: float | None=None, source_impedance_ohm: float=50.0, load_impedance_ohm: float | None=None, first_element: Literal['series', 'shunt']='series') -> LowpassFilter
