Abstract

A muting circuit detects data transitions during windows generated from received data, and counts the number of such transitions during the windows. A muting signal is produced in response to a predetermined count. If a transition occurs outside a window, the count is reset to zero, and an unmute signal is produced until the predetermined count is reached.
