Does waveform sampling method have any other advantage than better time resolution at high frequency for sampling fast signals?

I am working on a project that deals with signals with rise time as low as 1-2ns. To digitize the signal (so that it can be stored in digital computer for future reference) i needed a low power...

Can humidity change the resistivity, or simply it provides a leakage path via surface?

In an experiment i was measuring resistance of glass and found out that for a constant voltage applied across the glass plate, current was higher in high humid situation. I have taken a 2cm*2cm...
