Chander Sawhney Price. However, the typographical and bfher errors, which had crept in earlier edition, have been corrected. The book is intended as a standard text for students studying for their first degree Electrical, Electronics and Tnstrumentation Engine at Indian Universities and abroad, and tise for those appearing for A.
This has been necessitated on account of latest technological advances which put greater emphasis and reliance on Electronic Instrumentation. There is an extensive coverage of Flectrical and Electronic Instrumentation in this edition of the book as compared with the earlier ones. The coverage of Instrumentation portion is about pages out of a total of nearly pages.
The subject of Instrumentation has been developed in logical steps. There is an increased. The significant additions to the measurements portion are Transformer ratio bridges which fre fast replacing the conventional four arm a. The book though voluminous, covers two papers, i.
