Electromagnetism and DSL

In the electronics world everybody is using electromagnetism in around way. every(prenominal) signals be electromagnetic, so in the electrical engineering milieu electromagnetism is a leading topic of concern. One of our proscribed of class assignments was to converse a practicing engineer. I was assigned to question Mr. Gary J Trennison. Mr. Trennison is head engineer for Bell South. His study is reckon to DSL engine room (Digital Scribers Line Technology). During the interview I asked Mr. Trennison nigh the relationship of electromagnetic theory in the engineering lock purlieu, in any case about modern-day issues that the engineers face in their work environment that has a ball-shaped and societal impact. I also ask Mr. Trennison about environment issues related to professionalism and ethics. Electromagnetism is employ for various purposes in our mundane lives; one of the uses related to Mr. Trennisons work is DSL. DSL is a new way to apply our existing crap b id lines to deliver very proud-velocity internet connections. It works like ours existing, belatedly dial-up modem but without the slow dial-up part. DSL subscribers are always affiliated directly to the profit with their own secure, dedicated line. DSL modems are digital opposed dialup modems which are analog. DSL is accomplished by multiplexing different electromagnetic waves line into three separate bandwidths and frequencies.

presently our voice is carried everyplace the lower frequencies (30 Hz to 4 kHz) difference the high frequencies and bandwidth unused. The multiplexed electromagnetic signals are sen t through the copper telephone lines to the ! modem, so them modem demodulates the electromagnetism signal. As a conduct DSL technology has enabled us to utilize the unused higher frequencies for two-way high speed data transmittal. This way an ISP burn use the three hundred kHz to 700 kHz electromagnetic band for upstream transmission and the 1000 kHz and higher up very high speed...
