Questions and Answers

What is the principle of operation for a frequency counter?

  • Using a crystal controlled oscillator to generate the input signal
  • Gating the unknown input signal into the counter for a predetermined time (correct)
  • Measuring the amplitude of the periodic waveform
  • Converting the input signal into analog form for measurement

    • What is the function of the crystal controlled oscillator in a frequency counter?

  • Measuring the amplitude of the waveform
  • Counting the number of waveform cycles
  • Converting the waveform into square pulses
  • Generating a very accurate 100 kHz waveform (correct)

    • How are the frequencies at the outputs of each decade counter in the frequency counter?

  • Inversely proportional to the crystal frequency
  • Twice the crystal frequency
  • Dependent on the amplitude of the input signal
  • As accurate as the crystal frequency (correct)
