All About Electronics

Half Subtractor

Definition: The Half Subtractor is a digital circuit which processes the subtraction of two 1-bit numbers. In this, the two numbers involved are termed as subtrahend and minuend. In the subtraction procedure, the subtrahend will be subtracted from minuend. The circuit of Half subtractor consists of two inputs and two outputs. The inputs of the half subtractor circuit will be subtrahend and minuend. On the other hand, the output will be the difference and the borrow. The word “HALF” before … [Read more...] about Half Subtractor

Difference between Amplifier and Repeater

The major difference between amplifier and repeater is that an amplifier amplifies the weak signal and the noise associated with this signal also gets amplified. On the contrary, the repeater does not amplify the noise signal. Although a receiver also consists of an amplifier in it but apart from this it also possess a signal reshaping circuit which reshapes the distorted signal and amplifies the undistorted signal. One may think why these amplifiers and repeaters are used in electronic … [Read more...] about Difference between Amplifier and Repeater

Field Effect Transistor (FET)

Definition: FET is an acronym used for “field effect transistor”. It is a three terminal unipolar device in which conduction is manipulated with the help of applied electric field. The name itself gives a brief idea about its working principle, “field effect”, these two words clearly indicates it is a transistor controlled by electric field. Thus, it is also referred as a voltage controlled device in which only majority charge carriers are involved in the conduction mechanism. It comprises of … [Read more...] about Field Effect Transistor (FET)

Electronic Multimeter

Definition: The Electronic Multimeter is a device which is used for the measurement of various electrical and electronic quantities such as current, voltage, resistance etc. The multimeter name is given to it to define its ability to measure multiple quantities. It is provided with inbuilt power supply necessary for the functioning of the device. Any component such as a resistor, battery can be connected to its outer probes for the measurement of the electronic quantity. In order to … [Read more...] about Electronic Multimeter

Difference between Demultiplexer and Decoder

The main difference between demultiplexer and decoder is that a demultiplexer is a combinational circuit which accepts only one input and directs it into one of the several outputs. On the contrary, the decoder is a combinational circuit which can accept many inputs and generate the decoded output. The demultiplexer has selection lines to allow the input to follow one of the selected paths for generating it at the output. The decoder does not possess any selection lines as it has nothing to … [Read more...] about Difference between Demultiplexer and Decoder

Clapp Oscillator

Definition: The Clapp Oscillator is an electronic device that consists of single stage amplifier and a phase shift network.The basic function of an oscillator is to generate the sinusoidal signal and the same work a Clapp oscillator does. With the help of amplifier circuit, it provides the amplified signal to the phase shift network. This in return provides regenerative feedback to the amplifier circuit and thus sustained oscillations are produced. Have a look at the block diagram … [Read more...] about Clapp Oscillator

Oscillator

Definition: Oscillator is a circuit which utilizes positive feedback amplifier to generate sinusoidal waveforms of fixed amplitude and frequency. It is the major source of power in electrical and electronic instruments. The amplifier provided with the positive feedback can generate the sinusoidal signal even in the absence of any input. These signals are termed as oscillations, and hence the device is known as an oscillator. The positive feedback here implies the addition of some part of the … [Read more...] about Oscillator

Difference between Amplifier and Oscillator

The crucial factor which differentiates amplifier and oscillator is its usage. The amplifier is used as a multiplier circuit which is used for increasing the intensity of weak signal while the oscillator is used as a source in an electronic circuit. The main use of oscillator is for waveform generation. Another crucial term which makes the two components different is the type of feedback. The feedback used in the amplifier is negative feedback while the feedback used in the oscillator is … [Read more...] about Difference between Amplifier and Oscillator

Sample and Hold Circuit

Definition: The Sample and Hold circuit is an electronic circuit which creates the samples of voltage given to it as input, and after that, it holds these samples for the definite time. The time during which sample and hold circuit generates the sample of the input signal is called sampling time. Similarly, the time duration of the circuit during which it holds the sampled value is called holding time. Sampling time is generally between 1µs to 14 µs while the holding time can assume any value … [Read more...] about Sample and Hold Circuit

Parallel Binary Adder

Definition: The Parallel binary adder is a combinational circuit consists of various full adders in parallel structure so that when more than 1-bit numbers are to be added, then there can be full adder for every column for the addition. The number of full adders in a parallel binary adder depends on the number of bits present in the number for the addition. If 4-bits numbers are to be added, then there will be 4-full adder in the parallel binary adder. The parallel binary adder can be … [Read more...] about Parallel Binary Adder
