9.2 Design a program that uses the hierarchy of classes shown in Figure 9.18. Figure 9.18 Inheritance hierarchy of filter circuits. The Filter class should define the general attributes and behaviors that are common to all four types of filter circuits. This class should be defined as an abstract base class with pure virtual functions. Four derived classes should inherit the general properties from Filter and each class should also define some properties that are specific to a particular type of a filter circuit. The derived classes should also redefine virtual functions to process data for a specific type of filter. The program should allow the user to first select a specific type of filter circuit, and then call appropriate member functions to get, process/compute, and display data for that filter circuit
