Digital player for reproducing a digital signal sequence.

摘要

In a pulse width detector circuit, a high-level pulse width and a low-level pulse width of a digital signal derived by slicing an analog signal reproduced from a disc (1) at a predetermined level are independently measured (29, 30) and maximum or minimum values thereof in a predetermined time interval are stored, and an average value, sum or difference of the maximum or minimum high-level pulse width and the maximum or minimum low-level pulse width is calculated (37) to detect a correct pulse width of original data recorded on the disc.
