Introduction Recent advances in linguistics, in information theory, and in digital data-handling techniques promise to make possible the translation of languages by machine. This paper 1 proposes a system for translating languages by machine — with the hope that when such a system is worked out in detail, some of the language barriers can be overcome.

There are many methods to design digital circuits without hazard, such as the use of Boolean algebra, algebra hazard, karnaugh map, matrix method, VHDL, etc. However, these methods are not very suitable for the design of circuit system such as design of GALS circuits. In this case, synchronization is the most optimal method. 1. Introduction Hazard is the essence of digital circuits including synchronous circuit and asynchronous circuit. Hazard occurs as much as “autumn’s leaves” [1] and has adverse impact on the working of digital circuits. ...

SIGNAL PROCESSING IN THE TELEPHONE SYSTEM Until the introduction of the digital telephone, there was virtually no signal processing on the subscriber loop. Indeed, there was no need for it. The majority of subscriber loops were able to transmit voice signals with no particular difficulty and in cases where the lines were longer than usual, line ‘‘loading’’ was used with success. Signal processing has two major aims: (1) To improve the quality of signal transmission over the telephone communication channels....

Data and the Binary Code System ‘Data’, a plural noun, the term used to describe information which is storedand processed by is in computers. It is essential to know how such data are represented electronically before we can begin to understand how it can be communicated between computers, communication devices (e.g. facsimile machines) other data storage or devices. As a necessary introduction to the concept of ‘digital’ transmission, this chapter is devoted to a description of tha method of representing textual and numeric information which is called the ‘binary code’. ...

This application note introduces the concepts of digital modulation used in many communications systems today. Emphasis is placed on explaining the tradeoffs that are made to optimize efficiencies in system design. Most communications systems fall into one of three categories: bandwidth efficient, power efficient, or cost efficient. Bandwidth efficiency describes the ability of a modulation scheme to accommodate data within a limited bandwidth. Power efficiency describes the ability of the system to reliably send information at the lowest practical power level.
