Abstract
A decoder system for decoding signals such as Class IV partial-response signals. In the decoder system, threshold levels are used to distinguish between binary ones and zeros in partial-response signals. The threshold levels are adjusted by a feedback system to automatically compensate for effects such as signal dropouts.
