Abstract
Wave digital filters (WDFs), digital filters that are derived by mathematical transformations from passive analog circuits, are discussed. Design and implementation techniques of WDFs are described, and it is shown that the most flexible WDF structure is that derived from the analog lattice network. The use of WDFs in traditional frequency-selective applications, transmultiplexing, interpolators and decimators (i.e. circuits that increase or decrease, respectively), the sampling rate, and image processing applications are also discussed.<>
