- A&V• The amplitude (voltage) difference between the most positive and the most negative excursions (peaks) of an electrical signal.• Phase (chroma phase, hue, tint)--The relative timing of a signal in relation to another signal. If the time for one cycle of a signal is represented as 360— along a time axis, the phase position for the second signal is called phase angle expressed in degrees. The subcarrier phase of TV colors can be adjusted, and this changes the hue of the colors themselves.
