DelayAn outboard unit used to create time dependent effects where a source signal is sampled/recorded and replayed later by a adjustable amount, either singly or in multiples. The amount of delay results in a range of effects from chorus and slap back to rhythmic echo. Also used for time correction in large PA systems.

OscillatorIn analogue circuitry an oscillator is an AC generator whose output voltage is used to produce a signal of variable frequency usually from 20Hz up to 15kHz. The raw oscillator sound usually has one of a number of basic waveform shapes or timbres (sine, square or sawtooth) and is used as the basic sound source for many analogue synthesizers.

If two signals are identical but one is delayed by less than one complete wave cycle, the difference is described as a phase difference. This is normally expressed in degrees, with 360 representing a full wavelength.
