Abstract
A look ahead detector based on a delay line is used in a pulse amplitude qualifier circuit to qualify detected peaks in a system for the recovery of magnetically recorded digital information. The analog signal is delayed by one cell period to create a delayed replica which is applied to the peak detector. The difference between the analog signal and the delayed replica is applied to a hysteresis flip flop to create a qualifying signal based on a threshold value proportional to the analog signal to gate the peak detected in the delayed replica.
