Hi Zowb,
the waveform is produced by a oscillating circuit consisting of the coil and the wires to the coil and perhaps the capacity of the input amplifier. There are several ways to abate the waveform, e.g. by decreasing the quality of the oscillating circuit (I hope I found the right vocabulary since english is not my native language). You can do this with a resistor in row with the coil (little values shoult be good enough). But this also decreases the voltage of the pulse.
In electronics you would solve the problem with a retriggerable monoflop, wich is triggered with the first edge and kept in the triggered state when there are edges before the timeout. So if you want to do this in LV, it depends on the kind of signals you get. If you make an analogue aquisition or a timed polling of digital input you would use the
waveform peak detection.vi to find the lokations of pulses. If yopu use a buffered counter then the hardware gives you this locations directly. Then in a loop you throw all pulses with time differences less than the least expected pulse time at highest wheel speed and collect all passed times in a shift register. This should do it.
