Effect of RFI on the error probabilities of synchronizer circuits

This paper examines the ways in which radio frequency interference (RFI) affects the error probability of synchronizer circuits. Two effects are predicted analytically and demonstrated experimentally. In one case, RFI changes the effective sampling time of the synchronizer output. In the second, RFI...

Description
Summary:This paper examines the ways in which radio frequency interference (RFI) affects the error probability of synchronizer circuits. Two effects are predicted analytically and demonstrated experimentally. In one case, RFI changes the effective sampling time of the synchronizer output. In the second, RFI affects the nonlinear input-output pulsewidth transfer characteristic of a logic chain causing the pulsewidth distribution at the synchronizer input to be modified. It is shown that RFI may increase or decrease the error probability of a synchronizer circuit depending on circuit parameters and on the point of injection of the RFI.
