There are different numbering systems used in digital electronic circuits and computers. However, the numbering system used in one type of circuit may be different to that of another type of circuit, for example, the memory of a computer would use hexadecimal
Because of its widespread use, we will concentrate on addition and subtraction for Two’s Complement representation. The nice feature with Two’s Complement is that addition and subtraction of Two’s complement numbers works without having to separate the sign bits (the sign of
Section 1: Electrical interview questions and answers about switchgear and protection What are the functions of protective relays? To detect the fault and initiate the operation of the circuit breaker to isolate the defective element from the rest of the system, thereby
Everyone of us about the decimal numbers i.e. 1, 2, 3, 4, 5, etc. However, there are many other numeral systems that exist, like hexadecimal numbers for example:3F2Bor binary numbers for example:10101011.Some may think these numbers cryptic and meaningless. These hexadecimal or
Conversion from decimal number to binary number system is also essential to represent real-world quantities in terms of Binary values. The Sum-of-weights and repeated division by 2 methods are used to convert a decimal to Binary number. Sum of Weights Method The
Many different coding systems are used to represent data today. What is the importance of coding systems? To represent numeric, alphabetic, and special characters in a computer’s internal storage and on magnetic media, we must use some sort of coding system. In
