caused by the peak signal voltage being limited by the
circuits power supply voltage.
dB (decibel) a ratio of two voltages or signal levels, expressed by the
equation dB=20Log
10
(V1/V2). Adding the suffix u de-
notes the ratio is relative to 0.775V RMS.
DI(direct injection) the practice of connecting an electric musical instrument
