Bozidare,
think of 1- 999 RPM as 0.01667 - 16.67 revolutions per second. What kind of a transducer will You use? Will it be an analog tacho generator or some "digital" pulse transducer? If Pulse transducer how many pulses per revolution and therefore pulses per revolution per second will it produce? If analog how many volts per revolution per second will it produce? I hope this gives You a clue as to how to approach the initial problem. If analog use the AtoD converter if digital use some kind of timing scheme... either between pulses or over a number of pulses for increased resolution.
