Paper Abstract

A DVD disc signal measurement device is introduced in this paper. The device is fed high frequency signal and EFM+ signal from a DVD disc driver. By using EFM+ signal as input reference, the device is capable of recording all the peak (or bottom) values of a specified xT signal in an user defined duration. To improve the accuracy of the measurement device, the ac and dc components of high frequency signal are proceeded individually and then combined to give the corrected peak (or bottom) values. The corrected peak value is given by adding the dc component and the peak fo the ac component. The corrected bottom value is given by subtracting the peak of inverse AC component from the dc component.
