The TPU uncovered? (A PROBABLE technique.)

@duff - Excellent suggestion. The simplest kick test I've seen anyone mention here is shorting the terminals of a 9V battery with a length of wire. A fast diode on the positive terminal should prevent scope artifacts caused by reflection if any are present, no?

May I ask : is this 'kick' supposed to manifest itself only once when circuit is started ? Does it have such behaviour:
'kick' occurs if somebody starts circuit operation for the first time , then any subsequent restart of circuti does not generate this effect unless there is a some time period between each runs ? In other words circuit seems to have some inertia in generating this effect ?

@forest - There must be a time in between for the circuit to grow 'cold' again. Kicks occur with both the application of power and the removal of it. But I don't think that inertia has anything to do with it.

Here is a simple TDR circuit which I'm posting ONLY as a reference for observing reflections.

are both kicks generated always or that is diferrent for AC based and DC based circuits ? with removal of power does it occur only for DC powered circuits or for anyone ?
