Signal Noise and Distortion (SINAD)
Signal noise and distortion (SINAD) is the reciprocal of THD+N. SINAD takes into account both harmonics and noise.
The following equation yields SINAD:
You can use SINAD to characterize the performance of FM receivers in terms of sensitivity, adjacent channel selectivity, and alternate channel selectivity.

Real-world signals usually contain noise. A system can introduce additional noise into the signal. Total harmonic distortion plus noise (THD + N) measures signal distortion while taking into account the amount of noise power present in the signal.
