In the figure, A is a parallel - in, parallel - out 4 bit register which loads at the rising edge of the clock C. The input lines are connected to a 4 bit bus W. Its output acts as the input to a 16 4 ROM whose output is floating when the enable input E is a ... on the W bus at time t1 is 0110. The data on the bus at time t2 is Can anyone provide valid solution ? Answer: From 1030 To 970
