摘要:
A glitch filter identifies and eliminates positive edge and negative edge glitches without utilizing a high frequency sampling clock. The glitch filter comprises a programmable delay buffer string, two multiple input AND gates and a latch. The buffer string provides a plurality of incrementally delayed signals and utilizes them as signal samples thus simulating a high frequency sampling clock. The two multiple input AND gates serve to eliminate positive or negative edge glitches. The latch outputs the accurate filtered data without any positive or negative edge glitches.
