Lab :Signals with Multiple Frequency Components

I. Introduction:

For today lecture, we learned about the transfer function of the current.

To find the gain, we get the ration between Io/Iw. To find zeros, we find the roots of the numerator, to find poles, we find the roots of denominator

With the given graph, we have to find the ratio between Vo and I

Follow Professor Mason codes, we were able to graph the transfer function using log scale 

II. Signals with Multiple Frequency Components:
In this lab project, we will calculate the magnitude response of an electrical circuit and use this information to infer the effect of the circuit on some relatively complex input signals

We used AWG editors to type in custom graph 20*(sin(2Pi*x)+sin(4pi*x)+sin(40*pi*x))

The graph here is created using sinusoidal sweep

Here is our derivation for the pre-lab. The gain of V0/Vin is about 5.06*10^-4 -0.0159j

III. Conclusion:
For today lab, we learned about the transform function of electric circuit, we also did some matlab experiment to plot the gain with zeros and poles using log scale. For the lab, we did signals with multiple frequency components which we learned about sinusoidal sweep function in the waveform software
