What is the need of oscillator?
Answer
Oscillators are needed to generate continuous AC waveforms from a DC supply for clocking, communication, and signal processing.
An oscillator is needed to generate continuous, repetitive alternating current (AC) waveforms (like sine waves, square waves, or saw-tooth waves) without requiring any external AC input signal. They are fundamentally powered by a DC source.
They are vital as clock generators in microprocessors, carrier wave generators in radio/wireless communications, and signal generators in testing equipment.
