frd
(d, w)¶ Construct a frequency response data model
frd models store the (measured) frequency response of a system.
This function can be called in different ways:
frd(response, freqs)
Create an frd model with the given response data, in the form of complex response vector, at matching frequency freqs [in rad/s]
frd(sys, freqs)
Convert an LTI system into an frd model with data at frequencies freqs.
 Parameters
response (array_like, or list) – complex vector with the system response
freq (array_lik or lis) – vector with frequencies
sys (LTI (StateSpace or TransferFunction)) – A linear system
 Returns
sys – New frequency response system
 Return type
