SINAD Analyzer VI

Takes a signal in and performs a full Signal in Noise and Distortion (SINAD) analysis, including measuring the fundamental frequency tone and returning the fundamental frequency and SINAD level in dB. Wire data to the signal in input to determine the polymorphic instance to use or manually select the instance.

This VI is designed to process a single channel or multiple channels continuously, typically from within a For Loop or a While Loop.

THD Plus Noise in dB is the negative of the SINAD in dB.
