Final Project

For the final project in this lab, I was told to improve my AM radio. In order to improve the radio, I considered several options, like...

The heterodyne uses a local oscillator generating a constant frequency and multiplies it with the input RF signal in order to filter out...

In an AM radio, the Mixer multiplies the input RF signal from the antenna with a local oscillator frequency in order to produce signals...

In order to create a more efficient and better operating mixer for the radio, I needed to filter out unwanted frequencies from the mixer....

The goal of this lab was to develop and test an antenna for use in the AM radio. The antenna used a square loop design, constructed as...

One of the engineering challenges in creating an AM radio is dealing with the very low voltage these antennas create, usually on the...

Amplitude modulated signals require two frequencies to operate: the first forms the body of the wave, and is referred to as the 'carrier'...

In this lab, I created sound using a speaker, an amplifier circuit, and a function generator. To begin, I soldered wires to the leads of...

In this lab, I built and tested a common emitter amplifier circuit. Common emmiter amplifiers are built around a central transistor,...

In this lab, I learned about the operation and proper use of the various equipment available in the RF systems lab. We began by using the...
