8.1.10 THD + Noise
The total harmonic distortion (THD) of a signal is a measurement of the harmonic distortion, and 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 TMUX6121, TMUX6122, and TMUX6123 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 8-10 shows the setup used to measure THD+N of the TMUX6121, TMUX6122, and TMUX6123.
