IEEE 754 Implicit and Explicit 1 Representation
Represent $(2.5)_{10}$ in IEEE 754 Single precision standard: When 1 is implicit. When 1 is explicit. For the part A I am getting:- 0 100 0000 010 0000 And for part B:- 0 100 0000 1010 0000 In explicit $1$ we have to explicitly give memory to that leading $1$ and in implicit notation, we don’t allocate memory to that leading $1$. @Arjun Sir…...

MultiSubject (CO, DIgital, DS)
A 4-bit modulo-16 ripple counter uses JK flip-flops. If the propagation delay of each FF is 100 ns, the maximum clock frequency that can be used is equal to: Ans 2.5MHz. I think it should be $\frac{1}{16*10^{-7}} = 0.625MHz$ ... minimum number of comparisons that will be needed in the worst case by the optimal algorithm for doing this is Ans = 840 I am getting 860.
