Line 1:
There are two common types of '''delay''' found as modules:
*Analogue BBDs
*Digital Delays
The name derives from a line of people passing buckets of water along the line.
A well-known integrated circuit device around 1980, the Reticon SAD-1024 implemented two 512-stage analog delay lines in a 16-pin DIP. It allowed clock frequencies ranging from 1.5
By 2009, the guitar effects pedal manufacturer Visual Sounds recommissioned production of the Panasonic-designed MN3102 and MN3207 BBD chip that it offers for sale.
Line 14:
Despite being analog in their representation of individual signal voltage samples, these devices are discrete in the time domain and thus are limited by the Nyquist–Shannon sampling theorem; both the input and output signals are generally low-pass filtered. The input must be low-pass filtered to avoid aliasing effects, while the output is low-pass filtered for reconstruction. (A low-pass is used as an approximation to the Whittaker–Shannon interpolation formula.)
