Abstract:
1. A waveform generator comprising: a signal generator including a plurality of taps for outputting a plurality of transition signals; an algebra module having a data input port, a clock input port, and an output port, wherein said algebra module generates a tap selection signal on its output port in response to a data signal received on its input port; a switching module including a plurality of input ports each one electrically connected to a corresponding different one of the plurality of taps of the signal generator, said switching module having an input port receiving the tap selection signal from the algebra module and an output port for outputting a transition signal from the tap among the plurality of taps that is selected by the tap selection signal; and an output module having a transition signal input port in electrical communication with the output port of the switching module, a window input port in electrical communication with the output port of the algebra module, and a waveform output port which outputs a transition edge derived from the transition signal received on the transition signal input port, said output module also providing an internal clock signal to the clock input port of the algebra module, said internal clock signal derived from the transition signal received on the transition signal input port.
