It is no secret that digital oscilloscopes are sampled data instruments and do not acquire a continuous record of the input signal. We know from sampling theory that the input signal, properly sampled ...

Digital instruments sample analog waveforms and operate on the samples with the assurance that the data can be restored to continuous analog form. The sampling theorem states that a signal digitized ...

Engineers are always looking to make their designs more efficient. Don has a DSP technique that should ease your computational burden. Interpolation and approximation are thorny issues for software ...
