Lab 10 - Practical Integrator

Practical Integrator

Objective:

Use an oscilloscope to display time-varying signals

Process:

1. In class Professor Mason used an opened oscilloscope to showcase what is inside the electronic instrument and how it works. It consists of an electric gun accelerating electrons towards a phosphor-coated display screen. This alone only yields one dot on the screen and moves only when electrostatic deflection is applied to it. The deflection plates are orientated horizontally left to right and vertically up or down causing a continuous signal varying with time to be displayed.

2. Problem
Sketch a circuit's input and output waveform for 1kHz sine wave, triangle wave, and square wave

3. Data Collected

In class demonstration - sine wave

Thats Prof. Mason!
Noise in the background illustrated because resistor was removed

square wave

Cosine wave

Conclusion:

The overall demonstration was peculiarly interesting from start to finish. To understand the how the instrument works and follow through to the product it produces, was remarkable to see what you can actually do with the material that is taught in class. Unfortunately, our camera equipment is not up to par and therefore could not capture the measurements of the waves. Although removal of the resistor did yield scratchy waves and input of it gave more smooth ones.
