A control used to adjust the height of a pulse received from the detecting system.
Part of an amplifier to which a control signal is applied to vary the gain of the amplifier. The ability to externally vary the gain of an amplifier.
A control that allows adjustment of iris response speed of Auto-Iris lenses. When an oscillation or "chattering" (iris opens and closes rapidly in bright light) occurs, reduce the gain level until iris stops oscillating.
A device that changes the gain of an amplifier or circuit, often a knob that can be turned or a slide that can be moved up arid down.
A volume-controlling device manipulated by either a sliding fader or a rotating knob.
An adjustable control that changes the gain of an amplifier
A component for controlling the signal level of a device. Most often a variable resistor.
