Web15 Nov 2024 · The THD+N is different for these two levels, being lower for the smaller input level (<0.0015% at -8 dBFS vs <0.005% at -1 dBFS). These results are not surprising—harmonic distortion is known to increase with larger signal levels in many systems, particularly as the signal level approaches its maximum.

What Determines Total Harmonic Distortion Power Quality?

WebTHD stands for Total Harmonic Distortion and can be used to estimate the degree to which a system is nonlinear.

THD and THD+N – Similar, but not the same - Audio Precision

To understand a system with an input and an output, such as an audio amplifier, we start with an ideal system where the transfer function is linear and time-invariant. When a sinusoidal signal of frequency ω passes through a non-ideal, non-linear device, additional content is added at multiples nω (harmonics) of the original frequency. THD is a measure of that additional signal content not present in the input signal. Web15 Nov 2024 · Distortion measurements (THD, THD+N and IMD) are traditionally expressed in terms of percent.
