2) CODF Chapter 8, 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 to the right? 4) Use the Q Method to reduce the following to its minimum logic function: Y-Sm(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, t1 Using an original value of 110000112 and a mask of000011112. calculate the results of a bitwise AND, a bitwise OR, and a bitwise XOR for these values.

Explanation / Answer

2.fig 8.14 is not given

3.since it is a multiplexer circuit and according to working of multiplexer I.e.  4:1 multiplexer cirrcuit consists of 4 data input lines D0 to D3, Two select line as S0 , S1 and a single output line Y. The select lines (S1, S0),select one of the four input lines to connect the output line. The particular input combination on select lines selects one of input (D0 through D3) to the output. I.e

If S1=0 and S0=0 then Y = D0

If S0= 0 and S1=1, then Y=D1

If S0=1 and S1=0, then Y = D2

If S1=1 and S0=1 ,Y=D3

So here according to question S0=1 and S1=0 so output y=D2=1
