Hypothetical schema for sampling maxima and minima of a continuous analog signal.

I have just examined a hypothetical application of modern IC technology. What’s already available out-of-the-box is, that for every Analog – Digital Conversion, a single value can be generated. And today’s chips allow this to happen at 100Msps, resulting in a bandwidth of 50MHz. But for some reason, the goal might be desired, that for each of these conversions, a pair of values is generated, that accurately reflect what the maximum and minimum analog value was. As a result, a hypothetical ~oscilloscope~ could display a column of pixels, with one X-coordinate, instead of just one pixel, indicating one Y-coordinate. And so, this is the first of 3 diagrams I came up with:

My assumption is, that a 100Msps A/D Conversion will follow each of the above circuit’s 2 outputs…
