What component is used to divide the frequency of an input signal?

• A. Oscillator
• B. Frequency Division/Divider
• C. Counter
• D. Amplifier

Answer: (B)

Dividing the frequency means producing a signal that runs at a slower rate than the input by a fixed factor. The component designed for this purpose is the frequency divider. It takes the input clock and outputs a waveform that toggles after a set number of input cycles, creating a lower-frequency signal with a stable, known ratio to the input. For example, a divide-by-4 circuit gives one output pulse for every four input cycles. An oscillator creates the input frequency but doesn’t divide it. A counter counts input events and can be used to build a divider, but the named function is the divider itself. An amplifier changes amplitude rather than frequency.
