Electronics And Communication Objective

GE 0106- prefatory Engineering-II The objective of this subject go out help us to know the basic knowledge of Electronics. The concept of semiconducting materials, transistors, diodes, field-effect transistor, MOSFET their working principles, affectionate structure and working model. To know about the a.c to dc converting circuits corresponding half wave, exuberant wave rectifiers circuits. Also the filter motion of ripples utilise miscellaneous types of filter circuits. The various types of transducer working, aspect and uses will be discussed briefly and moving coil and moving entreat instruments, thermistors, thermocouple, LVDT their construction and working principles are discussed. The basic building of digital gate like AND, NAND, OR, NOR are studied. Also the conversion types of various reckon systems like hexa, decimal, octal, binary will be studied.
