Data Communications Risk in Distributed Computing – Part IV

Robert Davis Robert Davis Profile: Robert Davis

Signal fading is a decline in transmission strength. Fading can occur when a signal is transmitted by microwaves. Under certain conditions, the signal picked up by the receiving unit can be quite weak. A weak signal is more susceptible to transmission noise and error.

Signal distortion can result from lack of synchronization between the time datum is sent and the time they are received. Lack of synchronization typically occurs when a signal travels several paths with different delays in each path. This will result in distortion when there is overlapping in the receipt of data from the different signal paths.
