Question

What is the difference between the transient voltage and the voltage waveform peak?

Answer

The transient voltage is the peak voltage as calculated by passing a waveform acquired at a sampling rate of 2 MS/s through a high-pass filter (fc = 5 kHz) and then eliminating the 50 Hz/60 Hz component. The waveform peak is acquired at a sampling rate of 200 kS/s.
