Answer 1

Digital storage oscilloscope (DSO)

A digital storage oscilloscope (DSO) is an electronic instrument that measures and records electrical signals.
It converts the analog signal into a digital format and stores it in its digital memory.
The input analog signal is sampled and then converted into a digital signal at each sample time.
The sampling frequency should be not less than the Nyquist rate to avoid aliasing.
These digital values are then turned back into an analog signal for display on a cathode ray tube (CRT).
Digital storage oscilloscopes have two operating modes: single-shot and repetitive.
In single-shot mode, the oscilloscope acquires and stores one signal.
In repetitive mode, the oscilloscope continuously acquires and stores signals.
