INTRODUCTION

Electronics means study of flow of electrons in

electrical circuits. The word Electronics comes from

electron mechanics which means learning the way

how an electron behaves under different conditions

of externally applied fields. IRE - The Institution of

Radio Engineers has given a definition of

electronics as "that field of science and

engineering, which deals with electron devices and

their utilization." Fundamentals of electronics are

the core subject in all branches of engineering

nowadays.
