Electrical Engineering XYZ MCQs
A quartz crystal oscillator consists of:
- Both series and parallel frequencies
- Only series resonant frequency
- Neither series nor parallel frequency
- Only parallel resonant frequency
Correct answer: 1. Both series and parallel frequencies
Explanation: A quartz crystal oscillator can operate at both its series resonant frequency and its parallel resonant frequency, depending on how it is configured within the oscillator circuit. These frequencies are determined by the physical characteristics of the quartz crystal and the circuit design. Typically, for different applications, one of these resonant frequencies is chosen to be the operating frequency of the oscillator.
