Although a given waveform may contain frequencies over a very broad range, as a practical matter any transmission system will be able to accommodate only a limited band of (1). This, in turn, limits the data rate that can be carried on the transmission (2). A square wave has an infinite number of frequency components and hence an infinite (3). However, the peak amplitude of the kth frequency component, kf, is only l/k, so most of the (4) in this waveform is in the first few frequency components. In general, any digital waveform will have(5) 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.

(3)是()

A.source

B.bandwidth

C.energy

D.cost
