impinvar
performs the impulse-invariant method of analog-to-digital
transfer function conversion discussed in reference [2]:
It finds the partial fraction expansion of the system represented by
b
anda
.It replaces the poles
p
by the polesexp(p/fs)
.It finds the transfer function coefficients of the system from the residues from step 1 and the poles from step 2.
