7.11 THD + Noise

The total harmonic distortion (THD) of a signal is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency at the mux output. The on-resistance of the TMUX550x varies with the amplitude of the input signal and results in distortion when the drain pin is connected to a low-impedance load. Total harmonic distortion plus noise is denoted as THD+N. Figure 7-11 shows the setup used to measure the THD+N of the TMUX550x.
