Logic circuits are used to make specific ‘true-false’ decisions based on the presence of multiple ‘true-false’ signals at the inputs. In such cases, specially designed logic circuits are used. These are materials, such as silicon or germanium, doped (that is, they have embedded small amounts of foreign matter with chemical reactions), so that there is an abundance or lack of free electrons. In some cases microprocessors are used to perform many of the switching and timing functions of the individual logic elements. Linear amplifiers are used for sound and video signals, while non-linear amplifiers are used in oscillators, electronic power devices, modulators, mixers, logic circuits and other applications where amplitude reduction is required. The bipolar transistor was invented in 1948 to replace the triode vacuum tube. Introduction to Electronics ii Dedication Human beings are a delightful and complex amalgam of the spiritual, the emotional, the intellectual, and the physical. Engineering Physics I B.Tech CSE/EEE/IT & ECE GRIET 3 d) Atomic radius (r) â The atomic radius is defined as half the distance between neighboring atoms in a crystal of pure element. One of the advantages of microprocessors is that they allow different logical functions to be performed, depending on the programming instructionsstored The disadvantage of microprocessors is that they usually work sequentially, which could be too slow for some applications. 1 Instructor: Pei-Wen Li Dept.
