Binary Code Natural Binary Coded Decimal (BCD) Decimal BCD group of four binary digits represent 0000 a single decimal digit

ISA-based data acquisition and control board accept up to 8 analog inputs, produce 2 analog outputs, accept up to 67 digital (switch) inputs address, data and select lines. In addition, a spare AND gate and two spare NOR gates are made available, along with a small breadboarding area

FLIP-FLOPS Flip-flops are digital devices that have the ability to store binary information after the excitation input has changed. They are considered to be the basic memory cell for the majority of electronic binary data storage applications. This section explores the flip-flop from a functional perspective

Binary Arithmetic Binary arithmetic Addition - Augend+addend+carry-in Sum ....carry-out Subtraction - Minuend-subtrahend-borrow-in difference ...borrow-out

Positional Number System Number system use positional notation to represent value. The position of the character(numeral) in a character string (collection of possible numerals) indicate value as well as the character itself. Radix (base) is the number of numeral characters in the character set of positional number system. Position Weiaht is a constant that represents the value of a position. Different position has different weight. It is the integer power of radix

Introduction Ideally, the system parameters along with the signal variables have infinite precision taking any value between -oo and · In practice, they can take only discrete values within a specified range since the registers of the digital machine where they are stored are of finite length

6.1 Introduction The convolution sum description of an LTI discrete-time system can, in principle, be used to implement the system For an IR finite-dimensional system this approach is not practical as here the impulse response is of infinite length · However, direct implementation of the IIR finite-dimensional system is practica
