    A 1-bit ripple carry full adder uses 7 AND gates in parallel at the first level of inputs and use 2 OR gates at the second level.If each gate has the propagation delay = .002 micro second , then the delay at each bit adder module will be .004 micro second.What will be the time taken by 8 bit adder...

    1. 30 micro second
    2. 35 micro second
    3. 40 micro second
    4. none

    So what's your best guess?

    Sounds like a homework problem.
