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).
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...
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.
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,

PCB stands for Printed Circuit Board, which is a board made of non-conductive material with conductive tracks for electronic components.
PCB is used to mechanically support and electrically connect electronic components using conductive pathways.
It is commonly made of fiberglass, composite epoxy, or other non-conductive materials.
Components like resistors, capacitors, and integrated circuits are soldered onto the PCB to...
Capacitors store and release electrical energy in a circuit.
Capacitors store energy in an electric field
They can release the stored energy quickly when needed
Capacitors are commonly used in electronic circuits to filter signals or store energy
Examples: smoothing out voltage fluctuations in power supplies, timing circuits in oscillators
