Abstract: The present invention provides a system and method for introducing white noises into a digital audio signal so that there is progressive and cumulative degradation in audio quality after each successive reproduction of the audio sound signal in a fashion analogous to analog audio reproduction. The invention provides a white noise generator, and a digital entroping unit. In a preferred embodiment, the white noise generator is implemented by a hardware random number generator. The digital entroping unit controls the magnitude of white noise desired based on a random number generated by the random number generator, and adds the white noise to the input audio sound signal to produce a degraded audio sound signal. The magnitude of white noise can be controlled by using various masking and formatting of random number data.

Abstract: In a plasma display device and a driving method thereof, a switch for applying a voltage rising waveform to a scan electrode during an idle period and a first period is coupled between the scan electrode and a power source. The switch applies the voltage rising waveform having a first slope by being repeatedly turned on/off according to a first control signal during the idle period, and/or the switch applies the voltage rising waveform having a second slope (having a higher gradient than the first slope) by being repeatedly turned on/off according to a second control signal during the first period. As such, the scan electrode voltage is increased with the first slope during the idle period to perform a more stable reset operation. Also, when the idle period does not exist, the voltage of the scan electrode is increased within the first period to enable a normal reset operation.
