ABSTRACT:
Digital filtration is accomplished by splitting the incoming signal into phases. Each phase is then converted into a weighted sum reflecting the design of a prototype filter. Then the data is again split into phases at which time specific points may be interpolated and the data accumulated until a filtered signal has resulted. All of the steps can be easily modified after manufacture so that the filtration can handle variable bandwidth systems at low data rates, as well as implement a wide variety of filtering structures.
