In communications and electronics work, the term analog is used to mean a particular type of circuitry or manner of dealing with voltage and current. A good analog signal is absent distortion when compared to the original. A microphone converts sound waves (acoustical energy) into electrical energy—voltage and current. A speaker converts electrical energy into acoustical energy. Distortion of any kind along the path between source and destination is undesirable technically and may not be commercially acceptable to the viewer or listener. Electrically or electronically, an analog waveform is a representation of voltage ...
