Counting pulses can lead to very long sample times at low rpms if more than a

I know. But tell me how a Frequency to Voltage converter can increase
the precision?

if you measure the pulse width instead, you don't run into long sample
times at low rpms.

Another solution I've seen is to use a PLL frequency multiplier. :-)
