Abstract

A system has a first digital-to-analog (D/A) converter to receive a digital signal and to convert the digital signal into an analog pulse, a second D/A converter to cancel residual energy resulting from a previous pulse if a predetermined sequence of digital data is received, and a third D/A converter to control a falling edge of the analog pulse. Additionally, the system has logic to detect the sequence of digital data and to generate control data for at least one of the D/A converters from the digital data sequence thereby ensuring that the analog signal complies with the specified pulse mask template.
