Harmonic Distortion Analysis

Next
Harmonic Distortion analysis is a type of transient analysis in which a single frequency sinusoidal signal is applied to an input source and the resulting distortion measured in the output.

If a signal at a particular frequency is applied to the circuit input and if the circuit is not linear, signal level will be found at some frequencies other than the input frequency. In other words, distortion will occur. Harmonic Distortion analysis measures this distortion and provides plots of THD, THDN, SINAD, SNR, and Hm (m'th harmonic) vs F, and the peak and RMS versions of VIN, VOUT, PIN(Input Power), and POUT(Output Power).

The analysis makes extensive use of Periodic Steady State techniques to improve accuracy and speed.
