• The transient waveform consisting the fundamental component 50 Hz/60 Hz from a waveform sampled
at 2 MHz.
• The transient value measured from the waveform obtained by eliminating the fundamental component
50 Hz/60 Hz from having a sampled waveform pass through a highpass filter (fc = 5 kHz).
• Since voltage waveform display data reduced to 20 kS/s, the effect from a transient waveform may not
be reflected to the voltage waveforms.
