Abstract

This article describes a peak detector for a magnetic recording channel which is insensitive to noise on either edge of the readback signals. As shown in Fig. 1, the peak detector comprises a threshold detector 10 and a slope detector 11 which are provided with the readback signal on input line 12. The output of the threshold detector 10 is connected to the set input of the flip-flop 14 which functionally controls single-pole, single-throw (SPST) switch S1. The output of the threshold detector 10 is also connected to one input of gate 15. The output of slope detector 11 is connected to the other input of gate 15. The output of gate 15 controls a single-pole, single-throw (SPST) switch S2.
