A ring counter with 5 flip flops will have

Decimal number 1 = binary number 001 = A BC Decimal number 7 = binary number 111= ABC, Decimal number 3 = binary number 011= ABC Decimal number 5 = binary number 101= ABC . Hence result.

The largest negative number is 1000 0000 = -128.

Demultiplexer takes data from one line and directs it to any of its N output depending on the status of its select lines.

In a ripple counter the effect ripples through the counter.

1's complement of 0101 is 1010 and 2's complement is 1010+1 = 1011.

1000 = 5 or N = 10.

All AND inputs must be 1 and inhibit 0 for output to be 1.

If is made to be unity, the O/P count N₂ = e_i, N₁ = 6 = 000110.

Number of flip-flops = = 8.333 say 8

Modulus = 2⁸ = 256.
