Measuring Audio Amplifier Performance with MATLAB | Part 3

This presentation demonstrates the process of assessing several metrics to compare two amplifiers. In part 3 of this 3-part series, we will be demonstrating how to record the signal and calculate the metrics for comparisons -- Frequency response, Max. gain, THD, SNR, Cross-talk, MOS.
