Digital Logic The Autobiography Of Binary - 1080 Words

Digital Logic: The autobiography of Binary Calculators, watches, computers – eletronic devices of all kinds that immerse the information age that has so dautingly taking control of modern society. Stephen Rajkumar Samuels-Koothrapalli takes apart the casing of most prominent technologies, exploring the evolution of analog to digitial logic and it’s implications for the growth of contemporary eletronics. The development of digital logic circuits began with the creation of electromechnical relays by Jospeh Henry in 1853. Relays are devices that allow small currents residing in relay coils to close their contacts, permitting the flow of larger currents in an electrical circuit (Vogel, 2015); these relays are found in essentially all†¦show more content†¦This condensing of information into a single digit input, instigation of a process, followed by the output also being a single digit allows for easy pattern finding or in the case of Boolean algebra, the simplification of logic gates in a digital circuit. Furthermore, it can be seen that digital circuits utilise the converted information in two forms, combinational and sequential circuits. Combinational circuits operate as functions of input, with a consistent input reliably resulting in a consistent output e.g. an input of 01 into a circuit results in a 01 output, this process will remain, whenever this input is put into the circuit the 01 output will result (Lin, 2003). Sequential circuits differ in that their output can be affected by previous inputs and future inputs through the utilisation of memory elements that store previous logic values (Schibli Lee, 2015). This data retention is achieved through Flip Flops, memory elements capable of storing a single bit of information in binary form (Godse Godse, 2009). When grouped these form Registers whose sole purpose is the shifting and storing of binary data (Bakshi Godse, 2009). As seen in figure 1.2, output Z is a function of the External Input and the memory states. The ‘ function of input’ is ‘saved’ into the state, with the next signal from the external input being affected by the new internal input (Sequential SwitchingShow MoreRelatedElectronics and Communication Engineering (Ece) Syllabus Book R075299 Words   |  22 PagesSystems Electrical Technology Electronic Circuit Analysis Electronic Circuits Lab.
