Jack van‘t Wout,Maarten Waage,Aaldert Hofmantal systems possess many advantages over analog systems and there is an increasing trend towards converting analog signals into digital signals and then using digital systems to process the signals further.

The junction transistor,p, and are called emitter, base, and collector. The two possible types of transistor are shown in Fig 5.1 with their circuit symbols. The central region is very narrow in width, and has a much lower impurity concentration than the two outer regions.

Transistor characteristics and the operating point,sible. It is desirable that the largest possible output voltage be produced with the minimum of distortion. The optimization of the D.C operating conditions is done by a graphical method which uses two families of characteristic curves called the input and output characteristics.
