1.	Assume a 4-bit ripple counter has a failure in the second flip-flop such that it “locks up”. The third and fourth stages will __________(a) Continue to count with correct outputs(b) Continue to count but have incorrect outputs(c) Stop counting(d) Turn into molten siliconThe question was posed to me in examination.My doubt is from Counter Implementation and Applications topic in portion Counters of Digital Circuits
Answer» The CORRECT choice is (c) Stop counting Explanation: The RIPPLE counter WOULD stop counting because next flip-flop’s input DEPENDS on the output of the PREVIOUS flip-flop.
