- 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.- See also - cheby1
