Radio waves of constant amplitude can be generated with:
Radio waves of constant amplitude can be generated with:
Open in App
Solution
The correct option is D Oscillator
- Oscillator
Oscillator is an electronic circuit that produces a periodic and oscillating electronic signal, often a sine wave or a square wave. Oscillators also convert the direct current from a power supply to an alternative current signal. Radio waves are a type of electromagnetic radiation with wavelengths in electromagnetic spectrum. Thus, radio waves of constant amplitude can be produced by using oscillator with proper feedback.
