Exam 3: Data Transmission

The simplest sort of signal is a ________ signal,in which the same signal pattern repeats over time.

Delay distortion occurs because the velocity of propagation of a signal through a guided medium varies with frequency.

The maximum rate at which data can be transmitted over a given communication path under given conditions is referred to as the ________.

Because of delay distortion some of the signal components of one bit position will spill over into other bit positions causing ________ interference,which is a major limitation to maximum bit rate over a transmission channel.

The designer of a communications facility must deal with four factors: the data rate that is used for digital information,the amount of noise and other impairments,the level of error rate that is acceptable and the ________ of the signal.
