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?
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?
Darn...another keyboard ruined by coffee. Thanks for the laugh, anyway. It was worth it!
(rant chorus) You forgot the old standby which occurs about 2 weeks after your excuse #1:
"Payment is held up -- you sent us duplicate invoices." "You're net 180 and counting, I sent you a copy of the bill. It's not a second invoice. That's marked clearly, and the copy is watermarked "COPY -- NOT ORIGINAL" on the bottom of the invoice in 36 point type." "We have to have payables straighten this out -- we'll get back to you."
This is good for stretching net 150 out to net 2.4E2 or so. And when you're using scientific notation to estimate payment date, it's not a good sign. (end of rant)
My invoices go out at FTL, but the speed of the return can be quite slow. The customer claims that M is so large that it requires far too much E to square the aCcount. :)
The excuses can be legion......
"We have not received your invoice. Please send a copy."
"The person who signs the cheques is away, sick."
"The person who signs the cheques is away, on a course."
"The person who signs the cheques is away, on holiday."
"We have sent you a cheque, but it must have got lost in the post. We will send you another, but there will be a delay, because procedure requires that we receive the confirmation of cancellation before another cheque can be issued." That one is a well-used delaying tactic.
"We have not received internal confirmation that the goods have been delivered."
"..... but there *are* the goods, you are looking at them."
"..... but procedure requires that we receive internal written confirmation that the goods have been delivered."
"..... but you are looking at the bloody goods, there they are."
And worst of all was the UK MoD(PE), equivalent to the US DoD. Who paid the money ok, but then demanded it back, (with menaces), not because they hadn't received the goods, but because some precious internal 'pink slip' had not found its way to the correct civil service dept.
