### Q

#### Q

(1) Figure of merit of efficiency of a circuit or coil. (2) Ratio of inductive reactance to resistance in servos. (3) Relationship between stored energy (capacitance) and rate of dissipation in certain types of electric elements, structures, or materials [2] [9].

 Keyword(s): Q

#### QUALITY (OF SOUND)

The factor that distinguishes tones of pitch and loudness [10].
 Keyword(s): QUALITY

#### QUANTIZED WAVE

A wave created by the arbitrary division of the entire range of amplitude (or
frequency, or phase) values of an analog wave into a series of standard values. Each sample takes the standard value nearest its actual value when modulated [12].

 Keyword(s): QUANTIZED WAVE

#### QUANTIZING NOISE

A distortion introduced by quantizing the signal [12].
 Keyword(s): QUANTIZING NOISE

#### QUANTUM-MECHANICAL TUNNELING

The action of an electron crossing a PN junction because of tunnel effect [7].

 Keyword(s): QUANTUM-MECHANICAL TUNNELING

#### QUARTER-WAVE ANTENNA

Same as the MARCONI ANTENNA [10].
 Keyword(s): QUARTER-WAVE ANTENNA

#### QUIESCENCE

(1) The state of an amplifier with no signal applied. (2) The operating conditions that exist in a circuit when no input signal is applied to the circuit [6] [71 [13].

 Keyword(s): QUIESCENCE

#### QUIESCENT STATE

The period during which a transistor, tube, or other circuit element is not
performing an active function in the circuit [9] [13].
