13. A waveform-capture-device (WCD) comprising:
a time-to-digital converter (TDC);
a digital oscilloscope (DO); and
a tapped delay line (TDL) comprising a plurality of registers and a plurality of carry-chains (CCs),
wherein the CCs are configured to capture a digital waveform without encoding the digital waveform,
wherein each CC is used to buffer an input signal and wherein the registers are used to capture a waveform of the input signal on an edge of a clock, and
wherein each CC comprises at least one carry-element (CD) that passes the input signal to another CE after a time-delay.
