| These questions could be imp for comp..pls answer them if u know..they are from Oswal Comp papers..
1. Find the complement of F(a,b,c,d) using De Morgan's laws.Show the relevant reasoning. ( Is the question correct ?? )
2. Convert the following product-of-sums form into its corresponding sum-of-products form : F(x,y,z)=pi(2,4,6,7) ( How to do this ??) |

| i am not sure of the first question but the second is done using K map..!!
use K map to fill the corresponding cells with 0 [as it is a POS] and the rest of the cells will be the SOP..write them out using corresponding indices and simplify them..!
it sounds difficult but it is quite easy...!!! |

| i figured out another way ..though im not very sure of the logic.. convert 2,4,6,7 to their binary form.. complement it.. and convert back to integers.. ul get the SOP nos--5,3,1,0 now u can get F.. |

| it is F(X, Y, Z)= X'YZ + X'Y'Z soln: (X'YZ + X'Y'Z)' =(X'YZ')'.(X'Y'Z)' =(X+Y'+Z)(X+Y+Z') ??????But isn't it a solved paper??? |

| yea..i guz u can..! Using truth table is simpler than K map..isin't it..??
But i always like to do things the hard, standard complex way in computer so that i can use up whole time..!! |

| ______ put over the question and use the laws to simplify it..! I looked into it yesterday and i found out..! If the question is F(a,b,c,d) t hen its like a function in maths f(x)-->y
Using the four variables we must find the minterms..whose values would be given in the questn...!! And then to find the SOP... i got it now..
anyway thanks for the help..! |
