mkcoef Source #

Arguments

:: (Num a, Ix b, Integral b) 
=> (a -> a)

f

-> b

p

-> a

x

-> Array b a

h[n]

mkcoef takes the continuous impluse response function (one of the functions below, f) and number of points in the interpolation, p, time shifts it by x, samples it, and creates an array with the interpolation coeficients that can be used as a FIR filter.
