Transcribed Image Text:Q4 (a) Why does synchronisation failure occur?
(b) Suppose, you are building an embedded microprocessor system with a
10MHZ clock and use the circuit of figure Q4 (b) to synchronise an asynchro-
nous input which changes 100,000 times per second. Assume that a typical
flip-flop has been used for which the constants To and t are 0.4s and 1.5ns
respectively. If the setup time of the flip-flop is 20ns, calculate the mean time
between synchroniser failures.

(c) The circuit in Figure Q4 (c) consists of edge triggered flipflops. The second flipflop
receives the clock signal through a long slow path which results in delay. Answer
