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. |
