Q. What do you eman by Digital Circuits?
The use of nonlinear devices (BJT and FET) in constructing linear amplifiers. Although these devices are inherently nonlinear, their operation was confined to the linear portions of their characteristics in order to produce linear amplification of a signal. When these devices are operated in the nonlinear regions of their characteristics, the primary use lies in electronic switches for use in computers and other digital systems. Digital electronic circuits are becoming of increasing importance. Revolutionary advances in integrated-circuit (IC) technology have made it possible to place a large number of switches (gates) on a chip of very small size. Besides the advantage of utilizing less space, another significant advantage of digital systems over analog systems is their inherent immunity to noise and interference.
Digital building blocks (made up of transistor circuits) and computer systems have been presented in Chapter 6. Digital circuits are almost always purchased as ready-made IC building blocks. However, users of digital hardware must decide which technology is best suited for each case because competing technologies known as logic families are available. Digital circuit design is of course of great interest to engineers in the IC industry for designing and building digital blocks. The users of digital technology will certainly benefit from knowing what is inside the blocks they use.
