In the right, shifting bits are shifted towards right as: bit b7 moves to b6, b6 to b5 and so on . A zero is

inserted at the b7 position. It is to be noted that b7 represents sign bit. For positive numbers, the sign bit is

0 and for negative numbers sign bit. In the right shifting the sign bit remains at its position and propagates

too in the right direction. After shifting the bits of b1 once, the resultant bits pattern will be as follows:

bits b7 b6 b5 b4 b3 b2 b1 b0

b1(21) 0 0 0 1 0 1 0 1
