This book is intended to support the students of undergraduate engineering in the related fields of Electronics and Communication Engineering as well as Telecommunication Engineering courses for practicing laboratory experiments. It gives relevant information on the basic understanding of circuit configurations and connectivity of BJT and FET Amplifiers and Study of frequency response. It presents the design and test of analog circuits using OPAMPs, understand the feedback configurations of transistor and OPAMP circuits and the use of circuit simulation for the analysis of electronic circuits using PSPICE. It also provides various methods and techniques for conducting the experiment. Clear circuit diagrams and proper calculations have been provided for all the experiments and simple language has been used throughout the book for better understanding of the concepts for the students
