Unformatted text preview: . Show all steps. Consider 3 bits at a time (Out of the 8). The bubble will appear either as designed as follows (The output will be high when there is a bubble). or as . The truth table can be The function for the above truth table is The "Bubble Detect Circuit (BDC)" for the above function is shown below (implemented using only 3 input NOR's) The "Bubble Detect Circuit (BDC)" if applied to consecutive 3 bits will result in the overall circuit The worst case propagation delay of the BDC is When the output is high, it implies that the 8 bit input does not contain a bubble and vice versa. The worst case propagation delay of the entire circuit is The throughput of the circuit is ( ) ( ) ....
