Transfer function tanh(Tes)

[swagata]

Hi,
I need to build a transfer function ( see the attached screenshot)    

FS= (1-ZP.tanh(Te.s))/(1+ZP.tanh(Te.s))

s = control.TransferFunction.s
x=Tep*s
Fs=1/(Zp*np.tanh(x))

I am getting following error:

Error:
AttributeError                            Traceback (most recent call last)
AttributeError: 'TransferFunction' object has no attribute 'tanh'

The above exception was the direct cause of the following exception:

Error:
TypeError                                 Traceback (most recent call last)
<ipython-input-84-f6843dc03fc2> in <module>
----> 1 Fs=1/(Zp*np.tanh(x))

TypeError: loop of ufunc does not support argument 0 of type TransferFunction which has no callable tanh method

Can anyone help me on this code.

Regards,
