Patent ID: 7920979

Claim:
A signal generation circuit comprising: a data source configured to provide data that is to be represented by a signal to be generated by the signal generation circuit and conforming to a particular protocol; a waveform generation mechanism configured to generate a predetermined waveform of one or more predetermined waveforms when triggered wherein the predetermined waveform represents a band-limited pulse, wherein the full length of the predetermined waveform is at least twice the reciprocal of the cutoff frequency to be applied to the band-limited pulse; a triggering mechanism configured to repeatedly trigger the waveform generation mechanism at a plurality of times by repeatedly performing the acts of identifying and triggering as follows: an act of identifying a time that the waveform generation mechanism is to be triggered based on the data received from the data source; and an act of triggering the waveform generation mechanism to generate a predetermined waveform at the identified time.
