Make a Piramid with Ms.Excel



examples of the use of digital systems in their daily lives

A manufacturing plan needs to have a horn sound to signal quitting time.The horn sould be activated when either of the following conditions is met :

1. it's after 5 o'clock and all machines are shut down
2. it's Friday . the production run for the day is complete, and all machines are shut down

design a logic circuit that will control the horn . ( Hint: use variabfor logic input variables to represent the various conditions ; for example input A will be high only when the time of day is 5 o'clock or later).

logic gate with theory of De Morgan

Augustus De Morgan
a). (A/.B.C/)/ = A// + B/ + C// = A + B/ + C

b). (A/+B/C)/ = A//.(B/.C)/ = A . B + C/

c). (AB(CD)/)/ = A/ + B/ + C// + D// = A/ + B/ + C + D

d). (A+B/)/ = A/. B// = A/. B

e). ((AB)/)/ = A// + B// = A + B

f). (A/ + C/ + D/ )/ = A//C//D// = ACD

g). (A.(B+C/)/.D)/ =  (A/ + (B + C/)// + D/ = A/ + (B+C/) + D/

h). ((M+N/).(M/+N))/ = (M+N/)/ + (M/+N)/ = (M/.N) + (M+N/)

i). (((A.B)/.C)/.D)/ = A/// + B/// + C// + D/ = A/ + B/ + C + D/

5.The next step, make a list of images on the first page in a way
select references and then insert table of figures, then it will look as in the picture below


6. choose a formal format in the table of figures and press ok

7. finish



NB: if you change the order of every link that you create then simply block all the paperwork and then click F9 on the keyboard and update the entire table, then the entire order will be automatically stacking sequence
