  • Data generator for controlling pulse width
    Patent number: 5177481
    Abstract: A data generator generates input data for a pulse generator from source data corresponding to a desired pulse width in order to make the pulse generator generate an output pulse having the desired pulse width. In the data generator, the source data are converted into the input data for the pulse generator based on a predetermined conversion relation; the predetermined conversion relation is varied; the width of an output pulse of the pulse generator is compared with that of a calibration pulse having a predetermined pulse width; and a conversion relation between calibration source data corresponding to a pulse width of the calibration pulse and the input data is maintained when the width of the output coincides with that of the calibration pulse.
