Hello,

I have a transfer function of the system.I have another simulink circuit. I want to test how the system responds to the output of the simulink circuit.

how can i connect the output of the simulink circuit to the input of transfer function?

Hi Manaswini,

You can use the 'Transfer Fcn' block in Simulink to visualize the system's response based on the output of the Simulink circuit. You will need to connect the circuit's output to the block's input, and then connect the block's output to a scope to view the response. For more information on how the block models a linear system, please refer to the following documentation link:

You do not need to perform fft operation on the output of the circuit. The 'Transfer Fcn' block in Simulink is designed to work directly with time-domain signals. Refer to the following section on the documentation page which states that the input and output are 'time-domain' signals:
