How is frequency measured?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Frequency is measured using several instruments:
- Frequency counters: Digital devices that count cycles per second
- Oscilloscopes: Display waveforms and calculate frequency
- Spectrum analyzers: Show frequency distribution of signals
- Tachometers: Measure rotational frequency (RPM)
- Software tools: Audio analysis programs for sound frequencies
The choice depends on the type of signal and required accuracy.
