A digital representation of a waveform is generated based on signals received during a recording period. The received signals include a digital clock signal providing a determined number of clock pulses during the recording period, a plurality of binary digital signals defining, for each clock pulse of the determined number of clock pulses, a waveform state associated with the clock pulse. A digital representation of the waveform is generated and storing. The waveform has a duration based on the recording period and a profile based on the defined waveform states associated with the clock pulses of the determined number of clock pulses.
