Oscillator / Resonator/ Filter

(Oscillator): An oscillator is an electronic circuit that generates a repetitive waveform at a specific frequency. It produces a continuous output signal without the need for an input signal. Oscillators are crucial components in various applications, including signal generation for radios, clocks, and microcontrollers.

(Resonator) A resonator is a device that exhibits resonance at a specific frequency or frequency. It can be mechanical, acoustic, or electronic. In electronics, resonators are often used to stabilize or control the frequency of oscillators or filters by providing a precise frequency reference.

(Filter)A filter is an electronic circuit or device used to selectively allow or block certain frequencies from passing through while attenuating others. Filters are essential for shaping the frequency response of signals in communication systems, audio equipment, and various electronic devices. They can be categorized into low-pass, high-pass, band-pass, and band-stop filters based on their frequency passbands and stopbands.
