cheb1mag
response of Chebyshev type 1 filter
Syntax
[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
cheb1mag
is evaluated- h2
Chebyshev I filter values at sample points
Description
Square magnitude response of a type 1 Chebyshev filter.
omegac
=passband edge.
epsilon
such that 1/(1+epsilon^2)
=passband ripple.
sample
vector of frequencies where the square magnitude
is desired.
