- 10:09, 22 July 2024 diff hist +723 Digital systems/Clocking (Q897) Created claim: context (P66): Rauschen und Brummen sind größtenteils Geschichte. Der moderne Ton-Operator wird stattdessen von Knacksen und Klickgeräuschen heimgesucht: Clocking-Probleme. Mit zunehmend komplexen und vernetzten Systemen müssen wir nun auch hierarchische, mehrschichtige Taktungsinfrastrukturen sowie Abstastratenwandlung an Systemgrenzen verwalten und beherrschen.
- 10:06, 22 July 2024 diff hist +196 Digital systems/Clocking (Q897) Changed claim: context (P66): Hiss and hum are mostly a thing of the past. The modern sound operator is haunted by clicks and crackles instead: clocking problems. And with increasingly complex and networked systems, we need to manage and master hierarchical, multi-layered clocking infrastructure as well as sample-rate conversion at clock domain boundaries.
