Line 8:
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.
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.)
