Basic Harmonic Analyzer Measurement
PrintOverview
Given an input signal, finds the fundamental frequency and computes Total Harmonic Distortion (THD). You do not need to specify any other input. You can control the amplitude, frequency, and noise level of the input signal. A secondary low-amplitude 60 Hz is added to the fundamental by default. This program is a shipping example VI included with NI LabVIEW.
