Analog Devices bought this company in 1969, using their products to enter the world of analog to digital converters in a very big way. Other companies also offered commercially available ADC and DAC products, including Advanced Micro Devices, Analogic, National Semiconductor, Burr Brown, and Texas...
There are two types of computers, analog (模拟) and digital. Analog are devices that require human operation like the tide predicting machine made by Sir William Thomson, and digital is like a personal computer, which uses a series of codes and programs to calculate data.vip考试与评价(英语...
A satellite communications link, for example, may encode information in ASCII characters if it is textual, or pulse-code modulate and digitize it in binary-coded decimal (BCD) form if it is an analog signal such as speech. The resulting coded data is then encrypted into ciphers by using ...

This paper is a study of various electric signals, which have been employed throughout the history of communication engineering in its two main landmarks: the telegraph and the telephone. The signals are presented in their time and frequency domain representations. The historical order has been fo...
Imperial units, units of measurement of the British Imperial System, the official system of weights and measures used in Great Britain from 1824 until the adoption of the metric system in 1965. The U.S. Customary System of weights and measures is derived
peripherals, or peripheral devices, are sometimes called "I/O devices" because they provide input and output for the computer. Some peripherals, such as external hard drives, provide both input and output for the computer. 504 7.1 Paper Tape ...
During the first half of the 20th century, many scientific computing needs were met by increasingly sophisticated analog computers, which used a direct mechanical or electrical model of the problem as a basis for computation. However, these were not programmable and generally lacked the versatility ...
This application note presents a brief history of how the IEEE® Communications Society sponsored the IEEE P1901.2 working group, which developed a complete, robust low-frequency, narrowband powerline communication (LF NB PLC) standard. It discusses the high-level structure of the ...
