• If Wp is a scalar, then cheby1 designs a lowpass or highpass filter with edge frequency Wp. If Wp is the two-element vector [w1 w2], where w1. • It finds the lowpass analog prototype poles, zeros, and gain using the function. • It converts the poles, zeros, and gain into state-space form.

• If required, it uses a state-space transformation to convert the lowpass filter to a highpass, bandpass, 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.

Filjmi s barunom sobti na russkom yazike youtube. Careful frequency adjustment enables the analog filters and the digital filters to have the same frequency response magnitude at Wp or w1 and w2. • It converts the state-space filter back to transfer function or zero-pole-gain form, as required.

Dolph.m - Dolph-Chebyshev array weights%% Usage: [a, dph] = dolph(d, ph0, N, R)%% d = element spacing in units of lambda% ph0 = beam angle in.
