ABSTRACT:
A speed sensor for a marine vessel includes a correction circuit to correct any sensor non-linearities so that the sensor produces an output with a pulse stream having a constant pulse rate, and reduces the pulse-to-pulse variations of the pulse stream. The circuit can standardize the pulse stream to have a frequency corresponding to a standard rate.
