The logic function F(A, B, 0 = 2(1,3,5, 6) can be implemented using:
In a binary adder with two inputs X and Y, the correct set of logical expression for the output S (sum) and C (carry) are respectively
A certain multiplexer can switch one of 32 data inputs to its output. The number of control inputs in this multiplexer
Consider the following statements associated with the use of various adder circuits:
1. A ripple carry adder is a parallel adder in which the carry-out of each full-adder is the carry-in to the next most significant adder.
2. Serial adders are used where speed is more important than circuit minimization.
3. The look-ahead carry adder speeds up the process by eliminating the ripple carry.
4. Serial adders are faster than parallel adders
Which of the statements given above are correct?
Assertion (A): The multiplexer can be viewed as a function generator.
Reason (R): The multiplexer acts like a digitally controlled multi-position switch
Assertion (A): Using a decoder could have advantages over using a multiplexer.
Reason (R): The decoder is more economical in cases where non-trivial, multiple-output expressions of the same input variables are required
Assertion (A): The speed of operation of the parallel binary adder is high.
Reason (R): The parallel binary adder is said to generate its output immediately after the inputs are applied.
