This is one for the likes of Simon SECS, Stu MSD and anyone else who has in-depth knowlege of the rev counter

How does the standard cosworth rev-counter operate.

From what I gather it has the following connections

VCC
GND
Signal


VCC is battery voltage, GND is self explanitry

It is the signal I am interested in - what sort of signal is it? Is it voltage dependent or frequency dependent?

If it is frequency dependent, what frequency scale does it operate on?
