The most important factor in the accuracy of the digital oscilloscope is the frequency at which the waveform is sampled. To gain an accurate reading, sampling should follow the Nyquist rate, which states that a minimum frequency of double the highest part of the signal being observed. Less tha ...Digital oscilloscope

The Digital Oscilloscope In The Real World ' Posted By: Ewan Fisher
A digital oscilloscope often uses an analogue input, which is then converter into digital information using ADC. It samples voltages as a series of discrete waveforms, which are stored as digital information until there are enough of them to reassemble a true picture of what"s going on in the sampling area. As a result, while practical for interrogation and review, digital oscilloscopes may be eschewed in favour of analogue for some applications.
