Abstract
An assembly configured to prevent phase error includes an input unit, a filter unit, a slicer unit, a subtraction unit and an addition unit. The input unit provides an original audio signal. The filter unit selects one part of an original audio signal according to a preset bandwidth setting on the filter unit to form a first audio signal, and outputs said audio signal from a second output terminal. The slicer unit analyzes the amplitude magnitude according to a preset threshold amplitude to form a second audio signal. The subtraction unit subtracts the first audio signal from the original audio signal to form a third audio signal. The second audio signal and the third audio signal have the same phase retardation. The addition unit adds the second audio signal and the third audio signal to form a fourth audio signal.
