Logic Gates

Last updated on April 13th, 2019In digital circuits, Boolean operations are performed by logic gates. Basically logic gates are basic circuits that have one or more input and exactly only one output. Input and output values are logical values in the form of 0 (FALSE) and 1 (TRUE). This makes to describe or understand any circuit using a truth table. Any logic gate has no memory of it. In computer architecture the are seven basic…

Boolean Algebra

Last updated on April 13th, 2019Boolean algebra is a set of rules for manipulation of binary number system. These rules are developed by an English mathematician George Boole in 19th century. The binary number system is based upon truth values which are depicted by logical constants TRUE and FALSE or 1 and 0. Logical functions: The sentences or statements which have a decision structure i.e. which can be determined to be TRUE or FALSE are…

What is meant by Digital Signal Processors?

Last updated on April 13th, 2019Digital Signal Processor: Digital Signal Processor (DSP) process everyday signals like voice, audio, video, temperature, pressure, or position that is digitized then arithmetically influence them. A DSP is meant for performing mathematical functions like “addition, subtraction, multiplication, and division quickly. Signals ought to be processed in an order that the data they contain may be displayed, examined, or converted to a different sort of signals which will be of use….
