Definition of Basic Electronics & what are its Types?

 In this article we are going to discuss about what is Basic Electronics & what are its Types?


What Is Basic Electronics?

Electronics Device – A device made from I /c material which can perform basic operation such as rectification, amplification etc.

Electronics circuit- A circuit which contains at least one electronics devices the main component. Ex-amplifiers, oscillator, rectifier counter, multiplexer.

It is of two types:-

Analog electronic circuit-  an electronic circuit which can process an analog signal that is, where input and output are analog signals is called analog electronic circuit. Ex-amplifier, rectifier etc.

Analog electronic circuit

Digital electronic circuit – an electronic circuit which can process a digital signal (a signal in the form of 0 and 1) is called digital electronic circuit.Ex- counter, multiplexer, decoder etc.

Digital electronic circuit

Mixed signal circuit: – Analog to digital and digital to analog converter are called mixed signal circuit.

Mixed signal circuit

Advantage of analog circuit –

1. It can be designed to handle any amount of power.

2. As majority of the signal are analog in nature, they can be directly processed in an analog circuit.

Application of Diodes:-

1.      Rectifier:-a circuit which convert pure AC signal into pulsating D.C.signal.
Properties of pure A.C. signal:-

Periodic variation.

Bidirectional (above &below time axis).

Zero average value (dc. Value)/ zero dc.

D.C. value= avg . value of wave form:-

No harmonics (because it has only  One frequency and so also called signal plus one signal)/non-sinusoidal non-periodic signal have harmonic

Properties of pulsating D.C:-

Periodic variation

Unidirectional ( either above or below time axis)

Non zero average value ( non zero DC)

Contains harmonics

This is combination of AC& DC as it contains properties of A.C. ( periodic variation)
and also it has property of DC ( non zero avg. value)

So both AC and DC component are present.

Pulsating D.C. =A.C. component +D.C. component


2.      Regulator: - it is an electronic circuit which maintains the D.C. output voltage of a power supply stable irrespective of fluctuations in A.C. supply and variations in load current.

3.    Clipper: – A circuit which remove unwanted portion of wave form it is a wave shaping circuit.

4.      Clamper: – A circuit which adds DC to an AC waveform without changing its shape.

5.   Voltage multiplier: - A circuit which has AC input and produce a DC voltage as output which is a multiple of peak AC input .

6.      Switch :- Diode in forward bias ≡low resistance ≡on switch (R=0—ideal diode)
Diode in reverse bias ≡ high resistance ≡off switch (R=∞ — ideal diode)
