The fact that the great majority of functions which may usefully be considered as signals are functions of time lends justification to the treatment of signal theory in terms of time and of frequency. A periodic signal will therefore be considered to be one which repeats itself exactly every T...
Random signals also have finite average power and fall into the category of power signals. A transient signal is an example of energy signals, which start and end with zero amplitude. There are still other signals that cannot be characterized as either power signals or energy signals. ...
A result of the law of large numbers type is obtained for the cost of tracking a discrete almost-periodic signal when the deterministic optimal feedback law is used in the presence of independent random perturbations.doi:10.1080/00207178808906017...
The output of the notch filter will be the periodic component of the signal, while the input to the fictitious plant will be the non-periodic random component. An improvement to the basic feedback controller is also given to reduce this error by using continuous-time least-squares estimation....
A review about the properties of several types of tracerinput signals is given and in particular the stochastic signals are discussed. An estimation of the necessary measuring time shows, that true stochastic signals are unimportant for tracer experiments. The use of periodic pseudo-random binary ...
1h, i), demonstrating the establishment of the apical-basal polarity in somite cells and the formation of the apical lumen in somites. The F-actin staining with Phalloidin also showed a stronger signal on the apical surface of somites (Fig. 1h, i) and demarcated the elongated shapes of ...
