It one of the famous textbook for Engineering Students. This book is mainly useful for Students belogs to Electronics and Communication Engineering Background. Voltage-and current-feedback circuits, which discover wide application in various branches of equipment, are also used as frequently as could reasonably be expected as a piece of pulse systems. Among such circuits, which will appear every through thi substance, are the cathode-supporter, stage inverter circuits, contrast amplifiers, and operational amplifiers.
