Signal class overview

Signal is an abstract class from which the Generator and Filter classes are derived. It is used to define basic properties common to all Generator and Filter objects. For example, the name of the signal object, debugging functions, and the sampling rate are all handled by this class. Also, it can be used to dynamically resolve various derived functions when using a generic Signal pointer. You do not create instances of this class directly, but rather use the derived functions in Generator or Filter objects.

There are three functions critical to the organization of Signal objects. These three functions are undefined in the Signal class and must be defined in a derived class. The functions are:
