The result is a measurable reduction of modulation noise with a corresponding gain in sonic clarity.

The dual capstan drive lifted the cassette tape's spring pressure pad out of the way, enabling lower head wear, and lower modulation noise.

Periodic jitter produces modulation noise and can be thought of as being the equivalent of analog flutter (Rumsey & Watkinson 1995).

Wanting to capture the striking limpidity of the best CD's as well as their dynamics, both Maxell and TDK became concerned about a hitherto neglected aspect of tape performance known as modulation noise.

In telecommunication, equivalent pulse code modulation noise (PCM) is the amount of thermal noise power on a frequency-division multiplexing (FDM) or wire channel necessary to approximate the same judgment of speech quality created by quantizing noise in a PCM channel.
