6.1 Introduction

• Consider time-varying electrical signals from Cell phones, Home theatre system, Heart rate monitor, TV, Radio, Radar, Airplanes, Satellites and so on. Such signals in various applications are normally very weak. These signals are of the order of a few micro volts or milli volts with small energy, and they need reliable signal conditioning and processing ...
