To construct a 16K × 4-bit memory, how many 4116 ICs are required?
Solution:
In a half adder circuit, which gate is used to implement the carry (C)?
Solution:
What is the binary code where all successive numbers differ from their preceding number by a single bit?
Solution:
Which of the following statements about flip-flops are incorrect?
Solution:
In the Carry look ahead adder, we have the Generate and Propagate signals which are used to determine the next stage carry. To get the first carry, we need 2 AND gates, 1 OR gate, and 1 XOR gate
Solution:
If three P-MOSFETs are connected in parallel in the pull-up network, how are the N-MOSFETs connected in the pull-down network?
Solution:
We are implementing a NAND gate using a 2:1 multiplexer (MUX), and one of the inputs of the NAND gate is used as the select line of the MUX. What should be the inputs of the MUX?
(Assume A and B are the inputs of the NAND gate, and A is used as the select line.)
Solution:
IC 7493 consist of ________
Solution:
A 4-bit ripple counter consists of flip-flops, which each have a propagation delay from clock to Q output of 15 ns. For the counter to recycle from 1111 to 0000, it takes a total of ____________
