The counter shown in figure is built using 4 negative edge triggered toggle FFs. The FFs can be set synchronously when R = 0. The combinational logic required to realize a modulo 13 counter is-A-F= Q4 Q3 Q2 Q1B-F= Q4 + Q3 + Q2 + Q1C-F = Q4 + Q3 + Q2 + Q1D-F = Q4 Q3 Q2 Q1-B-F= Q4 + Q3 + Q2 + Q1

Question

APTITUDE CRACK · Accepted Answer

The correct option is  B F= Q4 + Q3 + Q2 + Q1  According to figure, output of combinational logic is applied to R of all FF N = 13 = (1101)2 The logic required is Q4 Q3 Q2 Q1 The gate used is a NAND. Y = Q4 + Q3 + Q2 + Q1 .
