Sahib:

It is not LC.

For example 1 mfd and 1 henry is about 160 Hz. There is nothing anywhere close to 1 mfd. Any capacitance is probably in the range of 0.0001 to 0.001 mfd. And I am seeing time periods in the 1 second range, actually longer, and not in the 1/100 second range.

It is simply a magnetic core effect. Have you ever made a counter using a square loop material and current pulses? In some ways a similar effect.

Electrically speaking, the magnetic core enhances inductance unless saturated and the property of inductance is to delay change of current allowing instantaneous change of voltage.

I have no idea. Kindly explain if possible.

Sahib:

Consider a square loop material. If you stay below saturation, then when you magnetize the material to some level and remove the excitation, then that last level pretty much stays at the last level with no excitation. Now apply more excitation in the same direction, but not going into saturation, then you develop a higher residual flux level. Keep doing this until you reach saturation. When saturation is reach the excitation current will jump higher and that is detectable as the end of the count.

By adjustment of parameters you can change the count to saturation.

To some extent this is an analog operation. Thus, if you wanted to count to 1000 in one stage there would be some variability in the number of counts to saturation.

Bring this down to only two levels and you have a very precise divide by 2 counter.

In the old days of computer core memories this is basically what was done.

Another way square loop materials were used was in a transformer oscillator to convert DC to AC.
