The input to an analog-to-digital converter (ADC) consists of a voltage that varies among a theoretically infinite number of values. Examples are sine waves, the waveforms representing human speech, and the signals from a conventional television camera. The output of the ADC, in contrast, has defined levels or states. The number of states is almost always a power of two -- that is, 2, 4, 8, 16, etc.
Demerit points The Demerit Points Scheme is a national program that allocates penalty points (demerits) for a range of driving offences. The scheme is designed to encourage safe and responsible driving. Along with financial penalties, demerit points provide a strong incentive to drive within the law.
DPST is short for double pole, single throw. Double pole means that the unit contains two identical switches, side by side, and operated by one single toggle or lever. This means that two separate input wires can be controlled by a flick of one toggle.
