Experiment 9 – Oscillator
Today’s Date – December 3, 2021
Introduction
In this lab exercise we had use a Hartley Oscillator as our local oscillator source for our radio. It is expected that this oscillator should produce a sinusoidal output that will be de...

Experiment 8 – Mixer
Today’s Date - December 2, 2021
Introduction
The mixer multiplies an RF signal with an oscillator signal to produce a number of signals at different frequencies. The desired output is known as the difference frequency, which in our rad...
