Properties:

An electronic device whose input signals control power from a source independent of the input signals and delivers output signals of greater amplitude with respect to current and/or voltage. The output signals characteristics are uniformly related to the input signals. It incorporates two or more channels of which at least one is controlled by triggering pulses of electrical energy, and another is for electrical impulses which are video frequency signals which are converted into visual presentations (pictures) by means of a cathode ray tube or other items.
