The gated SR latch in Figure 5.5a has unpredictable behavior if the S and R inputs are both equal to 1 when the Clk changes to 0. One way to solve this problem is to create a set-dominant gated SR latch in which the condition S = R = 1 causes the latch to be set to 1. Design a set-dominant gated SR latch and show the circuit.
