THD+N THD+N stands for Total Harmonic Distortion plus Noise. Harmonic distortion is the unwanted addition of new tones to the audio signal. These tones are harmonically related tones to the original ...

This said, Delft University of Technology, working with Goodix Technology, seems to have got right up amongst the hi-fi numbers with a 0.18μm BCD prototype IC that achieves 120.9dB dynamic range and ...

There are many ways to measure THD in practice, but [Michael Jackson] has an interesting video showing how he easily visualizes THD using LTSpice.

A critical measure for all audio components is distortion, typically specified as total harmonic distortion (THD) or total harmonic distortion + noise (THD+N). THD is defined ...

Audio Precision today introduced the APx555 audio analyzer, which Tom Kite, vice president of engineering at the company, described as offering unmatched analog performance with a THD+N specified ...

It delivers an unprecedented level of performance with 129dB SNR, -120dB THD+N, and low power consumption making it ideal for portable products such as smartphones, tablets, and digital music players.

Isn't THD important in the sound quality of a receiver? The lower the better? Also, when you see the 20 - 20,000 Hz versus 40 - 20,000 Hz, the higher number 40 will affect the sound quality won't it?
