Question

2) CODF Chapter 8, #1 Design the digital logic for segments c. and g of the seven- segment display driver truth table in Figure 8-14. 3) CODF. Chapter 8, #4 What is the binary value being output D1 from Y in the multiplexer circuit shown D2 to the right? 4) Use the Q Method to reduce the following to its minimum logic function: Y -Ym(2, 3, 6, 7, 10, 11, 14, 15, 18, 19, 22, 33,34, 37, 38, 41, 42, 45, 46, 49, 50, 64, 65, 68, 69, 72, 73, 76, 77, 80, 81, 129, 130, 133, 134, 137, 138,141,142,147) 5) CODF, Chapter 9, Using an original value of 110000112 and a mask of 000011112. calculate the results of a bitwise AND, a bitwise OR, and a bitwise XOR for these values.

Explanation / Answer

Question 2 : The truth table is missing.

Question 3 : Since the multiplexer circuit gives a single output at a time, depending upon the selection lines.

Here is the truth table for Multiplexer.

So, As the given slection inputs are S1 = 0 and S0 = 1, from the truth table we can see that for given selection input the output is given as D1.

So the output is D1 i.e D1 = 1, the binary output Y = 1.

S1 S0 Y 0 0 D0 0 1 D1 1 0 D2 1 1 D3
