Definition of "Audio Power Amplifier" |
An audio power amplifier is an electronic amplifier that amplifies low-power audio signals ,signals composed primarily of frequencies between 20 - 20 000 Hz, the human range of hearing to a level suitable for driving loudspeakers. It is the final electronic stage in a typical audio playback chain. / Diode Transistor Logic is a class of digital circuits that is the direct ancestor of transistor–transistor logic. It is called so because the logic gating function ,example, AND is performed by a diode network and the amplifying function is performed by a transistor in contrast with RTL and TTL. |
