OR gate is a device which has two or more inputs and one output. The output of an OR gate is logical 1 (high) only if one or more inputs are logical 1 (high). In Boolean algebra, the term OR is represented by plus (+) and the Boolean expression Y = A+B indicates Y equals … Read moreOR Gate | Symbol, Truth table & Realization
AND gate is a device which has two or more inputs and one output. The output of an AND gate is logical 1 only if all the inputs are logical 1. In Boolean algebra, the term AND is represented by dot (.) and the Boolean expression Y = A.B indicates Y equals A AND B. … Read moreAND Gate | Symbol, Truth table & Realization
The NOT gate is a device which has only one input and one output. It is a logical gate which inverts the input digital signal. That is why NOT gate is also known as Inverter. In Boolean algebra, the term NOT is represented by bar symbol (‾) and the Boolean expression indicates that Y equals not … Read moreNOT Gate | Symbol, Truth table & Realization
Photoelectric cell is the device which converts light energy into electrical energy. Depending upon the different photoelectric effects employed, the photoelectric cells are of following 3 types. Photoemissive cell Photoconductive cell Photovoltaic cell Photoemissive cell This cell is based on the fact that electrons are emitted from a photo-sensitive surface by the action of light. … Read morePhotoelectric Cell | Types & Applications
Decoder is a combinational circuit that has ‘n‘ input lines and maximum of 2n output lines. One of these outputs will be active High based on the combination of inputs present, when the decoder is enabled. It means that Decoder detect a particular code. The output of the decoder are nothing but the min terms … Read moreDecoders | Types & Applications
Radioactivity Definition The phenomenon of spontaneous emission of radiations by heavy elements is called radioactivity. The elements which show this phenomenon is called radioactive elements. Radioactivity was discovered accidentally by Antoine Henri Becquerel in 1896. α-particle: It is called as alpha particle. It is a helium nucleus having two protons and two neutrons ( ). β-particle: It … Read moreRadioactivity | Definition, Types & Uses
Parseval’s theorem It states that the sum (or integral) of the square of a function is equal to the sum (or integral) of the square of its transform. Parseval’s theorem is also known as Rayleigh’s energy theorem or Rayleigh’s Identity or simply energy theorem. Proofs of Parseval’s Theorem
Electric charge is a fundamental property of matter due to which electrical and other related effects are produced in the matter. The transfer of electrons from one object to another is responsible for the electric charging of the objects. Or Electric charge is the physical property of matter that causes it to experience a force … Read moreElectric Charge | Types, Properties & Charging Methods
Electrical energy sources are majorly classified into two classes i.e. Independent sources and Dependent sources. The independent sources are further divided into two types namely voltage source and the current source. There are four types of the dependent sources. They are as follows 1. Voltage Controlled Voltage Source (VCVS) 2. Voltage Controlled Current Source (VCCS) 3. … Read moreClassification of Electrical Energy Sources
Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small; typical sizes are around 100 picometers. Atom The smallest particle of an element is called an atom. An atom can take part in chemical combination and does not occur free in nature. The atom of the hydrogen is … Read moreAtomic Structure | Constituents of an Atom
