Q1:

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 Q1

B
F= Q4 + Q3 + Q2 + Q1

C
F = Q4 + Q3 + Q2 + Q1

D
F = Q4 Q3 Q2 Q1

ANS: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 .
