. If Ws is a scalar, then cheby2 designs a lowpass or highpass filter with edge frequency Ws. If Ws is the two-element vector w1 w2, where w1. It finds the lowpass analog prototype poles, zeros, and gain using the function.

It converts poles, zeros, and gain into state-space form. If required, it uses a state-space transformation to convert the lowpass filter into a bandpass, highpass, or bandstop filter with the desired frequency constraints. For digital filter design, it uses to convert the analog filter into a digital filter through a bilinear transformation with frequency prewarping. Careful frequency adjustment the analog filters and the digital filters to have the same frequency response magnitude at or w1 and w2. It converts the state-space filter back to transfer function or zero-pole-gain form, as required.
