Those light waves may be sent through a transparent medium as a laser beam or con tained within a fiber optic cable The conversion from high frequencyhigh speed electrical signals into light can occur in two general waysapplied directly to the power. The reason for that may be that the channel is bandlimited or that we are assigned a certain frequency band and frequencies outside that band is supposed to be used by others Therefore we are interested in the spectral properties of v arious modulat Husheng Li.

A digital signal is superior to an analog signal because it is more robust to noise and can easily be recovered, corrected and amplified. For this reason, the tendency today is to change an analog signal to digital data. In this section we describe two techniques, . Sensor. . Mining. Applications:. . Ubiquitous. . Possibilities. .

Editorials are opinion pieces for newspapers and magazines, either in print or online.. An editorial expresses an opinion about a current issue or topic. .

Modulation is the process of encoding the baseband or source information (voice, video, text) in a manner suitable for transmission.. It generally involves translating a baseband signal (or source) to a band pass signal, centered at a high carrier frequency..
