US 11,448,689 B2 · Electronic device, signal validator, and method for signal validation

Abstract

An electronic device, a signal validator, and a method for signal validation are provided. The electronic device includes a circuit board generating a plurality of signals and a signal validator. The signal validator records a current voltage level of each signal as a sequence code and records a time interval between the sequence code and a previous sequence code as a delay time corresponding to the sequence code when a voltage level of one of the plurality of signals changes. The signal validator sequentially determines whether the sequence code matches with a prearranged sequence code. When the sequence code matches with the prearranged sequence code, the signal validator determines whether each delay time corresponding to each sequence code exceeds a predetermined delay time. When the delay time is less than the predetermined delay time, the signal validator determines that the plurality of signals passes signal validation.
