Title:
DIGITAL DEAD TIME FUNCTION DEVICE
Document Type and Number:
Japanese Patent JPH04271409
Kind Code:
A
Abstract:
PURPOSE:To output data without contradictions even in the case of the change of the dead time due to some factor by adding a preliminarily determined dead time to the time of an internal clock to determine the output determinate time of data. CONSTITUTION:The output of a sampler (a) which periodically gathers input data is preserved in a preservation area (b). The time obtained by an output predeterminate time calculating part (c) is preserved together. The time of an internal clock (d) and the preliminarily determined dead time are added to obtain the output predeterminate time of data to be next outputted by calculation in the output predeterminate time calculating part (c), and data is outputted when a time comparing part (e) detects that the time of the internal clock (d) exceeds this calculated time. After one data is outputted, the value obtained by linear interpolation between both data is outputted from a data interpolating part (f) till output of the next data. Thus, data exactly sampled at the time after the dead time is outputted, and data is outputted without contradictions even in the case of the change of the dead time due to some factor.
