Method and system for evaluating CD player response to anomalies in a CD

摘要

A system (70) and methods (100,200) for evaluating the response of an optical digital disk player (20) to anomalies in optical digital disks (50) are provided. The system (70) includes a simulator (60) configured to provide digital simulated output signals simulating the output of an optical digital disk player (20) during playback of an optical digital disk (50) having an anomaly. The system (70) also includes digital-to-analog converter circuitry (68) to convert the digital simulated output signals to analog simulated output signals and provide the analog simulated output signals to processing circuitry (30). The processing circuitry (30) generates control signals based on the value of the analog simulated output signals, and provides the control signals as outputs.
