Gate  | A device or circuit which has no output until it is triggered into operation by one  | |
  | or more enabling signals, or until an input signal exceeds a predetermined  | |
  | threshold amplitude.  | |
Limiter  | A device or circuit whose   | |
  | predetermined level in spite of wide variations of   | |
Limiting  | The restriction of the maximum peak amplitude of a signal to a designated  | |
  | level.  | |
Muting  | The act of preventing signal from being output.  | |
Phase shift  | 1. A change in the displacement, as a function of time, of a periodic  | |
  | disturbance having constant frequency. 2. The magnitude of such a change,  | |
  | measured in fractions of a wavelength or in electrical degrees.  | |
Polarity  | See PHASE SHIFT  | |
QuickMAP  | The diagram outlining the processing components in a particular processing  | |
  | setup.  | |
QuickSET  | The group of component settings associated with a QuickMAP.  | |
A standard covering serial communications between computers and other  | ||
  | equipment.  | |
Serial cable  | A cable used to connect between two serial ports. The connectors used are  | |
  | typically   | |
Serial port  | A communications port located either on a computer or on computer  | |
  | controlled equipment.  | |
Threshold  | 1. The initial (observable) point of an effect, e.g., threshold of hearing. 2. A  | |
  | predetermined point, such as a minimum current or voltage, for the start of  | |
  | operation of a circuit or device.  | |
Window  | An interval during which a circuit is gated open to permit signal sampling.  | |
  | During this interval, a window is figuratively OPEN to the signal.  | |
