AC signals

In-Class Demonstration by Prof. Mason to display what AC signals look like

 

 sinusoidal wave

 

 

same wave at a higher frequency

the true value of the capacitor connected was 3.3 microfarads. could not solve for such capacitor

Freemat lab

The objective of this lab is to learn how to use freemat in order to solve mathematical matrices involving imaginary numbers.

 

use freemat to solve nodal analysis

 

 

 

 

assignment 2 solve matrices with imaginary numbers.

 

 

overall it is highly visible that using freemat, the tedious math becomes much more easy. in conclusion it is highly visible why this computational program is a very helpful tool for engineers.



Integrating and differentiating op amp

 

We proceed signals through with circuits involving Resistors Capacitors and op amp

 

integrating op amp  decrease in amplitude and similar frequency

 

 

 

 



Saturation. The voltage applied to the OP amp wasn't enough to apply the necessary change, so the output became a square wave with a capacitor-like exponential decay

differential op amp amplitude decrease ant there is a phase shift.
