Construct a BCD ripple counter using a 4-bit binary ripple counter that can be cleared asynchronously and an external NAND gate.

Draw the logic diagram of a 4-bit binary ripple down counter using the following. Flip-flops that trigger on the positive edge transition of the clock. Flip-flop that trigger on the negative edge transition of the clock.

Consider the circuit given below: MSB and LSB of mod 10 ripple counter act as clock to ripple down and up counter respectively. Initially all the counters were cleared and output of comparator was A=B. The clock pulse is applied. Find the minimum no of clock pulses required to make A=B again.

Consider the function: int fun(int n) { if (n==4) return n; else return 2*fun(n+1); } A MOD-16 ripple counter is holding the count $(1001)_2.$ What will be the count after "$(\text{fun}(2)+15)_{10}$" clock pulses? $(1000)_2$ $(1010)_2$ $(1011)_2$ $(1101)_2$

A ripple counter is made with three positive edge triggered flip-flops. If the output of previous lower significant bit flipflop is used as a triggering clock pulse of the next higher significant bit flip-flop, then the resultant counter is a A MOD 3 up counter B MOD 3 ... counter D MOD 8 down counter since all are positive edge triggered flip flops ,so shouldn't the answer be mod 8 up counter??

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 $\frac{1}{16*10^{-7}} = 0.625MHz$ Consider a system employing ... The 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.
