How do you make a transfer function in Python?

Construct a transfer function. The default constructor is TransferFunction(num, den), where num and den are lists of lists of arrays containing polynomial coefficients. To create a discrete time transfer funtion, use TransferFunction(num, den, dt) where 'dt' is the sampling time (or True for unspecified sampling time).

What is a transfer function graph?

A graph of the transfer function displays the ratio of cross-spectra values for two signals in a defined frequency range. It also shows the phase relationship between the signals. In the VibrationVIEW software, the user can compare two input channels or one channel and the drive (output) signal.
