How to construct an unknown signal from sparse periodic samples?
I have an unknown black-box that is generating a deterministic continuous periodic signal and the period is variable between 1 to 30 seconds.
When the black box is turned on, the period is fixed, ...

Increasing image resolution
I know of some oscilloscopes (DSA8300) that repeatedly sample at a few hundred kS/s to reconstruct a few GHz signal. I was wondering if this could be extended to 2D signals (photographs). Can I take a ...
