Abstract:
Disclosed is a probability density histogram display for a digital oscilloscope which shows a probability density histogram display of an input signal waveform alongside the conventional voltage-versus-time time-domain display of the waveform. The histogram shows the relative frequency of occurrence of voltage amplitude levels of the waveform. The histogram is optional and shown simultaneously with the time-domain display of the waveform.
