Class Information
Number: 341/131
Name: Coded data generation or conversion > Analog to or from digital conversion > Increasing converter resolution (e.g., dithering)
Description: Subject matter where, from a system having a quantizing interval corresponding to a nominally n-bit system, one obtains a system having an n+1 or greater bit system due to the application of an oscillating or periodic signal to the input signal.
