cheb1mag
response of Chebyshev type 1 filter
Calling Sequence
[h2]=cheb1mag(n,omegac,epsilon,sample)
Arguments
- n
integer : filter order
- omegac
real : cut-off frequency
- epsilon
real : ripple in pass band
- sample
vector of frequencies where
cheb1magis evaluated- h2
Chebyshev I filter values at sample points
Description
Square magnitude response of a type 1 Chebyshev filter.
omegac=passband edge.
epsilonsuch that 1/(1+epsilon^2)=passband ripple.
samplevector of frequencies where the square magnitude
is desired.
Examples
//Chebyshev; ripple in the passband n=13;epsilon=0.2;omegac=3;samples=0:0.05:10; h=cheb1mag(n,omegac,epsilon,samples); plot2d(samples,h) xtitle('','frequencies','magnitude')
