In this Post I am going to put 5 questios from Digital Logic.I will be posting the solutions tomorrow.Have a small practice.If you like the questions post in the comments so that I can increase the frequency and no.of questions.

1. Find the number of flip flops that will be complemented in a 10-bit binary ripple counter to reach the next count after 1110001011?

2. How many 16 x 4 RAMs are required to achieve a memory with a capacity of 64K and a word length of 8 bits?

3. An n-bit twisted ring counter (Johnson’s ring counter) can have how many different output states?

4. How many Boolean functions on two independent Boolean variables a and b are dependent on either a or b or both?

5. Determine the minimum number of input NOR gates needed to realize the four variable function f(A, B, C, D) = ∑(0,1,2,6,8,9,10,11,14,15). Inputs are available in both prime and non prime form.
