A 3-bit gray counter is used to control the output of the multiplexer as shown in the figure (A2 is MSB and A0 is LSB). The initial state of the counter is 0002. The output is pulled high. The output of the circuit follows the sequence
1
I0, 1, 1, I1, I3, 1, 1, I2
2
I0, 1, I1, 1, I2, 1, I3, 1
3
1, I0, 1, I1, I2, 1, I3, 1
4
I0, I1, I2, I3, I0, I1, I2, I3
