Abstract
A pulse detection sensing system which provides an output signal only when a maximum voltage peak is detected. The system has a comparator which generates a comparator output signal when an output signal generated by the transducer of the system is equal to or greater than a threshold signal. The comparator is coupled to a peak follower and a sample/hold circuit which increases the voltage of the threshold signal to the level of the head output signal when the output signal attains a zero slope and has equaled or exceeded the set threshold value.
