What is the function of a transistor in an oscillator circuit?
In an oscillator circuit, a transistor is used to provide amplification and feedback to sustain oscillations, allowing the circuit to generate periodic waveforms such as sine waves, square waves, or triangular waves.

See lessExplain the operation of an astable multivibrator.
An astable multivibrator is a type of relaxation oscillator that continuously switches between two unstable states, generating a square wave output with a predetermined frequency determined by the RC time constants of the circuit.

See lessWhat is pulse-width modulation (PWM)?
Pulse-width modulation is a modulation technique used to encode information on a digital signal by varying the width of the pulse while keeping the frequency constant, commonly used in power control and motor speed regulation.

See lessExplain the process of frequency demodulation.
Frequency demodulation is the process of extracting the original modulating signal from a frequency-modulated (FM) carrier wave, typically achieved using circuits such as a phase-locked loop (PLL) or a frequency discriminator.

See lessDefine frequency modulation (FM).
Frequency modulation is a method of encoding information on a carrier wave by varying the frequency of the wave in proportion to the amplitude of the modulating signal, commonly used in radio broadcasting and communication systems.

See lessWhat is the purpose of a capacitor in a tuned circuit?
The capacitor in a tuned circuit provides capacitive reactance that cancels out the inductive reactance, resulting in resonance at the desired frequency and selective frequency response.
