Electromagnetism and DSL

In the electronics world everybody is using electromagnetism in nigh way. every(prenominal) signals argon electromagnetic, so in the electrical engineer butt on electromagnetism is a leading topic of concern. One of our forbidden of class assignments was to converse a practicing engineer. I was assigned to reference Mr. Gary J Trennison. Mr. Trennison is head engineer for Bell South. His study is intend 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 milieu, in any case about present-day(a) issues that the engineers face in their work environment that has a spheric and societal impact. I also ask Mr. Trennison about environment issues related to professionalism and ethics. Electromagnetism is employ for various purposes in our quotidian lives; one of the uses related to Mr. Trennisons work is DSL. DSL is a new way to apply our existing hair c all lines to deliver very proud-velocity internet connections. It works like ours existing, recently dial-up modem but without the slow dial-up part. DSL subscribers are always connected 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. shortly our voice is carried everyplace the lower frequencies (30 Hz to 4 kHz) difference the higher(prenominal) frequencies and bandwidth unused. The multiplexed electromagnetic signals are sent through the copper telephone lines to the modem, so them modem demodulates the electromagnetism signal. As a allow DSL technology has enabled us to utilize the unused higher frequencies for two-way high speed data transmittal. This way an ISP throw out use the three hundred kHz to 700 kHz electromagnetic band for upstream transmission and the 1000 kHz an d supra very high speed... !
