This project consisted of the design, construction, and comparison testing of two implementations of analog pulse-width modulation Class D audio amplifiers. The main goal of the project was to maximize the efficiency of the amplifier designs while maintaining a high-power, low-noise output signal. PCB testing confirmed that the amplifiers met our goals of greater than 90% efficiency, less than 1% total harmonic distortion and greater than 50 W output power.
