Summary

Total Harmonic Distortion (THD) and THD+N are key metrics for signal fidelity, particularly in audio and precision analog systems. Multiplexer can introduce distortion depending on the On-Resistance characteristics, with certain operating regions delivering optimized performance. By examining the measurement setups, RON curves, and real application cases, designers can better understand when to consider THD performance and how to minimize the affects.
