Encoding methods and Modulation schemes 25.P.1 Computers use digital signalling‚ digitals signals are represented by the base 2 numbering system “Binary”. Binary bits are shown as 1 or 0‚ where 1 means ON and 0 means OFF. In a network where digital devices exist‚ digital signalling will be used. Dependant upon the encoding method used‚ a high voltage on a communications medium can represent a logical 1 and a low voltage of can represent a logical 0. Different methods of encoding exist these

Lecture 1: Introduction to Programming 2013/14 Academic Year By Prof. Elijah I. Omwenga Introduction to Programming Program: The term program refers to a set of instructions that instructs a computer on what to do. Programs are Solutions to Problems. These instructions are written using programming languages. A program can instruct a computer to: – Read/ accept Input data – Calculate or compare – Store data – Write or display Output The term software refers to a computer program or set

PULSE MODULATION TECHNIQUES INTRODUCTION • Modulation is the process of frequency translation in which any one parameter(Amplitude‚ frequency or phase) of high frequency carrier signal is varied in accordance with instantaneous value of low frequency modulating signal. • Modulation is either analog or digital. INTRODUCTION • Many signals in modern communication systems are digital • Additionally‚ analog signals are transmitted digitally • Digitizing a signal results in reduced distortion

Binary Fission in Bacteria Bacteria are microscopic organisms made up of one cell and they do not have a nucleus but a loop of DNA. When bacteria‚ reproduce asexually the DNA loop is copied so that there is some for each new cell. The bacterial cell deivides into two by making a new cell wall. This type of asexual reproduction is called binary fission. Spore Production in Fungi Pin mould is a fungus which grows on bread
