| | Digital Filters as Physical Models |
 | | For example, robust, rapidly time-varying, nearly lossless digital filters (such as needed, e.g., for a guitar string simulation) can be developed more easily using a physical approach, and conditions for the absence of unnatural artifacts become more clear. |
 | | digital waveguide models have been used for distributed media, such as vibrating strings, bores, horns, plates, solids, acoustic spaces, and the like [,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,]. |
 | | Vaidyanathan and Mitra [] developed a class of digital filters containing both the WDFs and the Gray-Markel normalized ladder structures [], and proved low passband sensitivity to coefficient quantization and the absence of limit cycles, even under time-varying conditions. |
