cupyx.scipy.signal.cheb1ap(N, rp)[source]#

Return (z,p,k) for Nth-order Chebyshev type I analog lowpass filter.

The returned filter prototype has rp decibels of ripple in the passband.

The filter’s angular (e.g. rad/s) cutoff frequency is normalized to 1, defined as the point at which the gain first drops below -rp.
