Overview

Given an input signal, finds the fundamental frequency and computes Signal, Noise, And Distortion (SINAD). SINAD is defined as the ratio of Signal plus Noise plus Distortion and Noise plus Distortion. You do not need to specify any other input. You can control the amplitude, frequency, and noise level of the input signal. The default signal includes a secondary tone at 11.87 kHz. This program is a shipping example VI included with NI LabVIEW.
