cheb1mag(1) Scilab Function cheb1mag(1)
NAME
cheb1mag - response of Chebyshev type 1 filter
CALLING SEQUENCE
[h2]=cheb1mag(n,omegac,epsilon,sample)
PARAMETERS
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.
