- cupyx.scipy.signal.lp2lp_zpk(z, p, k, wo=1.0)#
Transform a lowpass filter prototype to a different frequency.
Return an analog low-pass filter with cutoff frequency wo from an analog low-pass filter prototype with unity cutoff frequency, using zeros, poles, and gain (‘zpk’) representation.
z (ndarray) – Zeros of the transformed low-pass filter transfer function.
p (ndarray) – Poles of the transformed low-pass filter transfer function.
k (float) – System gain of the transformed low-pass filter.
