1. What is Sinusoidal Oscillator?
A sinusoidal oscillator is an electronic circuit that generates a continuous sine wave output without any input signal, using positive feedback and a frequency-determining network like LC or RC.
2. What is Oscillation?
Oscillation is the repetitive variation, typically in time, of a signal or current. In electronics, it refers to the generation of alternating signals like sine waves or square waves.
3. What are the Types of Sinusoidal Oscillation?
The two main types of sinusoidal oscillation are damped oscillation, where amplitude decreases over time, and undamped oscillation, where the amplitude remains constant without external energy input.
4. What is Damped Oscillation?
Damped oscillation occurs when the amplitude of an oscillating signal gradually decreases due to energy loss, typically through resistance, until the oscillation eventually stops.
5. What is Undamped Oscillation?
Undamped oscillation is when the amplitude of the waveform remains constant over time, often achieved by supplying continuous energy to the system to overcome any losses.
6. What is Tank Circuit?
A tank circuit is an LC circuit made of an inductor (L) and capacitor (C) connected together. It stores energy and determines the frequency of oscillation in oscillators.
7. What is Oscillatory Circuit?
An oscillatory circuit is one that generates periodic signals like sine waves using energy exchange between inductance and capacitance components in the circuit.
8. What are the Advantages of Oscillation?
Oscillation is useful for generating clock signals, radio frequencies, audio tones, and carrier waves. It is essential in communication systems, timers, and signal generators.
9. What are the Essential Components of Transistor Oscillator?
Essential components of a transistor oscillator include a transistor (amplifying device), a feedback network, a frequency-determining tank circuit (LC or RC), and a DC power supply.
10. What are the Different Types of Transistor Oscillators?
The main types of transistor oscillators include Hartley oscillator, Colpitts oscillator, Phase-shift oscillator, Wien bridge oscillator, and Crystal oscillator, based on the feedback and frequency network used.
