Counters

Q1: Select the response that best describes the use of the Master Reset on typical 4-bit binary counters.

A When MR1 and MR2 are both HIGH, all Qs will be reset to zero.

B When MR1 and MR2 are both HIGH, all Qs will be reset to one.

C MR1 and MR2 are provided to synchronously reset all four flip-flops.

D To enable the count mode, MR1 and MR2 must be held LOW.

ANS:A - When MR1 and MR2 are both HIGH, all Qs will be reset to zero.

I think that Master determines the state of the slave, these two will never be equal in circumstance, therefore, when the slave is low, the master is high and vice versa. The slave is the o/p of the circuit, the mod is 16 having 16 AND Gates and 4 Input Gates each.
