Talk:UC (noise reduction)

Possible ToDos
A list of possible ToDos:


 * As publications on this system are rare, we should try to add any WP:RS discussing this to the "Further reading" section.
 * Try to find links to PDFs of the Hohmuth (1987) and Milde (1988) key sources for improved reader convenience.
 * List of UC compressed Eterna/Amiga/Nova records.
 * Photo of a Ziphona HMK-PA2223 turntable with built-in UC expander (also photos of its PCB and the "UC" logo).
 * Photo of an Eterna/Amiga/Nova record's deadwax showing the "U"/"CU"/"DU" code as part of the runout code.
 * Block diagram and excerpts of the original circuit diagram.
 * More detailed functional description.
 * More detailed technical specs (also sorting out if the maximum compression is 4:3:4 or 5:3:5 - sources differ on this)
 * Frequency and spectral curves.
 * Links to digitized UC compressed records played back with and without UC expander.
