Confronting Measurement Uncertainty in Signal Generation - Part 2: Interpolation Overshoot

Eric Hsu 2019.05.07

It is common to find a gap between ideal conditions and reality. When you generate the desired signal, you need to understand that hardware implementation may cause a certain number of errors to the o
