Several methods of indirectly measuring total harmonic distortion (THD) in a power amplifier by measuring characteristics of the input and output waveforms are presented. The relative accuracies of each method is discussed. While the emphasis is on practical methods that can be implemented in a automobile car radio, sensing THD levels within 1% of the target level can be realized.
