// Finding lowpass filter order with specifications // passband edge = 0.35, stopband edge =0.675, // passband ripple =6 dB, stopband attenuation = 5 dB wp=0.35; ws=0.675; rp=10; rs=30; [n,wn]=cheb1ord(wp,ws, rp, rs) |  |  |
Finding order of Chebyshev filter of type-1
[n,Wn] = cheb1ord(Wp,Ws,Rp,Rs) [n,Wn] = cheb1ord(Wp,Ws,Rp,Rs,'s')
Normalized passband edge frequency.
Normalized stopband edge frequency.
Allowable passband ripple in dB.
Allowable stopband attenuation in dB.
Computes the complex cepstrum (Xh) of a real sequence X. The desired length of the cepstrum can also be specified in the second argument N. The values of cepstrum are different for different lengths of the cepstrum specified. However, the values of Yh are independent on the values of the specified cepstrum length. The number of samples delay Nd introduced to the real sequence is required for inversion of complex cepstrum in correct sequence.
