Cheby1函数用法
WebIf 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 < w2, then cheby1 designs a bandpass or bandstop filter with lower edge frequency w1 and higher edge frequency w2.. For digital filters, the passband edge frequencies must lie between 0 and 1, where 1 corresponds to … WebTo obtain the transfer function form, use two output arguments as shown below. [b,a] = cheby1 (n,R,Wp,'s') designs an order n lowpass analog Chebyshev Type I filter with angular passband edge frequency Wp rad/s. It returns the filter coefficients in length n+1 row vectors b and a, in descending powers of s, derived from the transfer function ...
