Technical Paper / Book Excerpt

More InfoLess Info
Digital filters are used for two general purposes: separation of signals that have been combined, and restoration of signals that have been distorted in some way. Analog (electronic) filters can be used for these same tasks; however, digital filters can achieve far superior results. The most popular digital filters are described and compared in the next seven chapters. This introductory chapter describes the parameters you want to look for when learning about each of these filters.
