PT2399 - The Valve Wizard
... A delay-control resistance of less than 1kΩ is not recommended, due to excessive current demand. With a 100Ω delay resistor a delay time of 25ms is achieved with most samples. A zero-ohm delay resistor (dead short) gives almost no further decrease in delay time, and is not recommended. Latch up: If ...

At low frequencies this time is negligible. But when the frequency of operation is high and the signal being processed is the magnitude ...

Dither
Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images. Dither is routinely used in processing of both digital audio and video data, and is often one of the last stages of ""mastering"" audio to a CD.A typical use of dither is converting a greyscale image to black and white, such that the density of black dots in the new image approximates the average grey level in the original.
