Experiment 1: Audio Monitor Construct and test an audio amplifier using the LM386. This circuit will be used
again in other labs, so you'll want to save it.
Experiment 2: Carrier Oscillator In this experiment you'll construct an RF oscillator that will be the foundation of
a functioning low-power AM broadcast transmitter.
Experiment 3: Buffer Amplifier This is the second stage of the AM broadcast transmitter project. You'll
refresh your knowledge of op-amps and frequency response measurements as you build this important stage.
Experiment 4: AM Modulator This is the last stage of the transmitter -- you'll be on the air
with a 100 mW signal after completing this circuit.
Experiment 5: AM Detector This experiment concludes the AM sequence. A classic diode detector
circuit is constructed to demodulate the AM signal from the transmitter.
Experiment 6: Voltage Controlled Oscillator A Voltage Controlled Oscillator (VCO) is constructed
and characterized in this experiment. VCOs are important building blocks in modern communication systems, so this is an important
Experiment 7: Phased Lock Loop Building on the knowledge from Experiment 6, you will learn about
Phase Locked Loops (PLLs), which are also essential ingredients in today's state-of-the art RF systems.
Experiment 12: RS-232 This experiment explores the EIA RS-232 interface. While this interface
is now seldom seen in personal computing, it's still an important in quite a few industrial applications. The classic MC1488 and MC1489 ICs
are utilized. Terminal emulation is provided by EZ-Term, which can be downloaded from the software page.
