Data Rate and Bandwidth
{"Image DocumentName": "Data Rate and Bandwidth", "Image ImageDescription": "any transmission system has a limited band of frequencies. this limits the data rate that can be carried. square have infinite components and hence bandwidth. but most energy in first few components. limited bandwidth increases distortion. have a direct relationship between data rate & bandwidth. Although a given waveform may contain frequencies over a very broad range, as a practical matter any transmission system (transmitter plus medium plus receiver) will be able to accommodate only a limited band of frequencies. This, in turn, limits the data rate that can be carried on the transmission medium. A square wave has an infinite number of frequency components and hence an infinite bandwidth. However, the peak amplitude of the kth frequency component, kf, is only 1/k, so most of the energy in this waveform is in the first few frequency components. In general, any digital waveform will have infinite bandwidth. If we attempt to transmit this waveform as a signal over any medium, the transmission system will limit the bandwidth that can be transmitted. For any given medium, the greater the bandwidth transmitted, the greater the cost. The more limited the bandwidth, the greater the distortion, and the greater the potential for error by the receiver. There is a direct relationship between data rate and bandwidth: the higher the data rate of a signal, the greater is its required effective bandwidth.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
