The earliest analog computers were special-purpose machines, as for example thetide predictor developed in 1873 by William Thomson (later known asLord Kelvin). Along the same lines,A.A. Michelsonand S.W.Strattonbuilt in 1898 aharmonic analyzerhaving 80 components. Each of these was capable of...

which is the key to the the regulator the operational amplifier, analog electronic circuit function. The speed and the actual speed is compared to the quantitative amount of feedback, the motor speed control. Closed loop DC speed control system could inhibit the feedfor 调整系统从开环的DC速度对...
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 ...

After the furor over the potential Koran burnings last week, I had a look at the precedents, which it seems are everywhere, from Harry Potter to the Bible. For thousands of years, all religions and ideologies have been burning each others’ texts. ...
it converts digital signals received from the Data Link layer, into analog signals and loads them on the physical media. On the receiving computer, it picks analog signals from the media and converts them into digital signals, and transfers them to the Data Link layer for further processing....
