Bandwith and frequency

I this lab we will investigate a simple wave receiver. We will analyze the bandwidth and the quality factor

here is a picture of the circuit built

 

 

here are the calculations

on the right side we have the theoretical calculations and in the left we have the measured values.

we have seen that as we increase the frequency our current will decrease. and as we increase the resistance in the circuit the quality factor decreases
 

Frequency Response and filters

Objective

to verify the reaction of high and low pas filters

we will build a simple circuit using 1k resistor and 1 micro Farad Capacitor

Here is the circuit

 

 

 

Here are the calculation for the low pass filter

Notice that the voltage is taken off the capacitor

 

 

 

 

 

Here are the calculations for the high pass filter

Notice that the voltage is taken from the Resistor

 



 

 

After the experiment we found out that the filters actually filter voltages. high pass removes the low frequency voltage and the low pass filter removes the high frequency filters.

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.
