Convention Paper

Pre- and De-Emphasis - A Forgotten Necessity

Authors: Brock-Nannestad, George

AES Convention 110 · Paper 5360 · May 2001

Abstract

A number of physical limitations are inherent to analogue recording media, and for this reason compromises have to be accepted. In order to widen the frequency range of recordings, mechanical, optical, and magnetic recording have used pre-emphasis at recording which is then suppressed again by a complementary de-emphasis at replay. The paper traces the parallel development in all three fields of analog recording.
