Abstract:

A discussion is given of several topics which are considered fundamental to a consideration of digital techniques. These include time sampling, amplitude quantitization, and selected comments on number systems and computers. Since the functional elements of sonar systems can be described in mathematical terms, it is inferred that these elements can, in principle, be implemented or simulated by either analog or digital hardware. A discussion of specific applications is given to demonstrate that the choice of techniques depends on practical considerations. Two different uses of digital techniques are described, depending on whether or not the operation being performed must be carried out on a real time basis. Author
