Q2. What is a rectifier?
Ans. 
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).
• Rectifiers are commonly used in power supplies to convert AC to DC for electronic devices.

• They can be half-wave, full-wave, or bridge rectifiers.

• Examples of rectifiers include diode rectifiers and silicon-controlled rectifiers (SCRs).

Q3. What is modulation?
Ans. 
Modulation is the process of varying one or more properties of a high-frequency periodic waveform, called the carrier signal, with a modulating signal.
• Modulation is used to encode information on a carrier signal for transmission.

• There are different types of modulation techniques such as Amplitude Modulation (AM), Frequency Modulation (FM), and Phase Modulation (PM).

• Example: In AM, the amplitude of the carrier signal is...read more

Q4. What is sampling?
Ans. 
Sampling is the process of selecting a subset of individuals from a larger population to represent the whole.
• Sampling helps in making inferences about the population based on the characteristics of the sample.

• Common sampling methods include random sampling, stratified sampling, and cluster sampling.

• For example, a survey conducted by selecting a random sample of households to represent the entire city's population.

Q5. What is an oscillator?
Ans. 
An oscillator is an electronic circuit that produces a repetitive electronic signal, typically a sine wave or square wave.
• An oscillator generates a periodic waveform without any external input signal.

• It uses positive feedback to sustain oscillations.

• Common types of oscillators include LC oscillators, crystal oscillators, and relaxation oscillators.

• Oscillators are used in various applications such as signal generation,

Q1. What is transistor? Working principal of it.
Ans. 
A transistor is a semiconductor device used to amplify or switch electronic signals.
• Transistors consist of three layers of semiconductor material: the emitter, base, and collector.

• The working principle of a transistor involves controlling the flow of current between the emitter and collector using the base.

• Transistors can be used in various electronic devices such as amplifiers, switches, and oscillators.

• Common types o...read more

Q2. What is a thyristor?
Ans. 
A thyristor is a solid-state semiconductor device that acts as a switch, controlling the flow of electric current.
• Thyristors are used in power control applications such as dimmer switches, motor speed control, and power supplies.

• They have three terminals: anode, cathode, and gate.

• Thyristors have a four-layer structure and are capable of handling high currents and voltages.

• Common types of thyristors include silicon-cont
