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: FRD
