5/30 Signals with Multiple Frequency Components

     The purpose of this lab is to verify the equation of transfer function: at very low frequencies, the capacitor has infinite impedance, the circuit becomes a simple voltage divider. At very high frequencies, the capacitor;s impedance is zero, the capacitor behaves like a short circuit.

Pre-Lab calculation:

The following photos are the result of our experiment :

This is the graph of output and input voltage. Yellow line is the output and the blue one is the input.

Using the sweep function we will have another photo: 

Summary

        In today's class, we learned the concept of transfer function: 

here is the graph of the transfer function: 

Also, the following picture is the related equation for transfer function: 

This is the example we did during the lecture time:
