章節(jié)摘錄
A signal may be random in a variety of ways, perhaps the most common type of randomness is in the amplitude of a signal waveform, illustrated in Fig. 2.8(a). In this case future values of the signal cannot be predicted with certainty, even when its past history is taken into account. Fig. 2.8 (b) shows another common form of randomness, of the general type displayed by the Morse-code message just mentioned. Here the signal is always at one or other of two definite values but the transitions between these two levels occur at random instants. Signals in which the times of occurrence of some definite even or transition between sates are random arise in many diverse fields of study, such as queuing theory, nuclear particle physics and neurophysiology, as well as in electronic communications. Fig. 2.8 (c) show a signal possessing both the common types of randomness so far mentioned, and represents an electrocardiogram (ECG), or recording of the electrical activity of the heart. The heartbeat is somewhat irregular, so that the timing of successive ECG complexes has a random component; furthermore, the waveshape itself is not exactly repetitive in form.
