What is Peak to Peak?

[Harry Dellamano]

Let's say you have a 100KHz waveform which contains a positive 5V peak
pulse, 5uS later a negative 5V peak pulse repeating every 5uS to form 100KHz
repetition rate.. The pulses have 10nS rise, fall and pulse width times. Is
the peak to peak value 5V or 10V?

TIA,
Harry

The long name of the concept is
"absolute value of positive peak minus negative peak".

How you choose your peaks is up to you.

Ok, we all agree it is 10V. Now let's say that when the 5V pulses return to

zero they overshoot by one volt then return to the zero baseline. Is the
peak to peak now 10 volts or does the overshoot now reduce it to 6V?

You seem to be wriggling for some reason Harry.

Trouble is, you used the critical word "waveform"
in your original post.

You might argue that the peak-peak voltage of each
individual pulse is 6V, but the peak-peak voltage of
the *waveform* still has to be 10V.

I did some work for a very large British company, formerly a
government arm, and THEY invoiced ME for the work I'd done.

I'll take a guess...... BT?
