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.
Drivers incur demerit points for certain traffic offences. The number of demerit points incurred depends on the offence and how likely it is to cause a crash. Demerit points are incurred whether the offence is committed in South Australia or interstate. 16 to 20 demerit points you lose your right to drive for four months. 2  more than 20 demerit points you lose your right to drive for five months. 3  If you hold a Learner's Permit or Provisional Licence and you accumulate 4 or more demerit points you could lose your right to drive for at least six months.
