In audio, dither can be useful to break up periodic limit cycles, which are a common problem in digital filters.
32.
Digital filters also don't have to worry about stray coupling paths and shielding the individual filter sections from one another.
33.
Audio filters can be implemented in analog circuitry as analog filters or in DSP code or computer software as digital filters.
34.
Window functions generated for digital filter design are symmetrical sequences, usually an odd length with a single maximum at the center.
35.
Furthermore, one can readily modify the coefficients of a digital filter to make an adaptive filter or a user-controllable parametric filter.
36.
The standard digital filter, available with both additive and subtractive synthesis, is known for its rather extreme self-oscillation at higher resonance settings.
37.
In image processing, it is considered to be a type of digital filter, more specifically an edge filter, called the Laplace filter.
38.
The digital filter can be made to have a near-ideal transfer function, with low in-band ripple, and no aging or thermal drift.
39.
Moreover, just like 1D filters, most 2D adaptive filters are digital filters, because of the complex and iterative nature of the algorithms.
40.
One solution would be to overclock the conversion elements, introduce a digital filter and follow them with an acoustical low pass filter.
