Abstract : An apparatus is disclosed which permits a high speed waveform, for example in the form of a series of analog data pulses, to be sampled and converted into a series of digital values. Each analog data pulse is applied in parallel to a multiplicity of A/D converters and to one or more level detectors. Each level detector provides a strobe when the voltage of the analog data pulse crosses a reference threshold. The strobes are applied to delay means whose outputs are a multiplying of delayed strobe pulses which have been delayed by predetermined amounts. Each of the multiplicity of A/D converters samples the analog data pulse in response to the particular delayed samples the analog data pulse in response to the particular delayed strobe applied thereto and provides a digital value of that sample. The largest of the digital values from each of the A/D converters is provided as the output of the apparatus for each analog data pulse.
