Gregory explains what is THD - Total Harmonic Distortion, using the circuit from the last video. • An oscilloscope is used for a THD measurement, and the limitations are shown, as the harmonic distortion of the oscilloscope front-end masks the oscillator THD. • THD is a measurement of distortion, used as the main figure of merit in audio applications, where the non-linear behavior is characterized using the power at the harmonics of the fundamental signal. • Watch my video about Nonlinearity and Distortion • • Distortion and Nonlinearity Basics • Watch my explanation about the Wien Bridge Oscillator • • Wien Bridge Oscillator with AGC and PLL • Support the channel, becoming a Patron: • / allelectronics • 00:18 - Oscillator prototype • 01:12 - Circuit behavior • 02:12 - Total harmonic distortion • 07:10 - THD measurement • 07:56 - Measuring distortion with oscilloscope • 11:18 - Final circuit details
