That small C' + D thing ruined my day but i came back today to understand this again and found these comments talking about it and now i am relieved !! thank you NESO!
119 video in your playlist... alll videos are so easy to understand... today is my exam and it helps me a lot... thanks.. Neso Academy... Thank you so much
Thanks Neso Academy ... you are life saviour ... Not studied dld whole semester but now I am well prepared... keep uploading videos .. and helping students like me...
Thank u very much for your way of description. It really helped me understand the topic and solve similar questions in an extremely short span of time.
If we oppose the rule of sir karnaugh then C'D'+C'D+CD=C'.(D'+D)+CD=C'+CD=(C'+D)[by using distributive law]... I m not sure... It may also the result of this expression... somebody please tell me that is it right or wrong? .... But in k map we can't take combination of 3 1's... hence we get C'D... So.. what is the right answer... #Neso#academy please tell me....
Sir, your videos are awesome, thank you. But in this videos if we consider C and D as selection lines then will it affect the overal funtionality.? please reply Sir
Yes, the inputs will then depend on A and B. But whatever, I don't think it's going to help u now as it have been 5 years since your comment. But I hope, may this reply remind u of your old days.😄
Simplifying function: F = BC' + C'D + A'BD...........(i) Let A&B are the select lines. For AB=00, from(i) F= C'D For AB=01, from(i) F= C' + D For AB=10, from(i) F= C'D For AB=11, from(i) F= C'
Sir I saw your a lots of lecture on digital system , these are very easy to understandand ,after wathing these videos I understood many things. but I have a problem ,one question regarding combinational circuit.......the question is given below.... 1.AB represents a two bit binary number that can be any of the values 00,01,10,11.Similarly CD represents another two bit binary number that can be any of the values 00,01,10,11.Design a combinational logic circuit which gives HIGH output when the numbers AB and CD are equal. plz sir send me answer and logic about that.
+sanjit kumar mahato Not sure...but i think you should just make a function with 4 variable; ABCD. Then dress 16 rows, from 0 to 15. Mark all the minterms, put them in a K-map, then simplify the function. Last step is implementation
How to implement the Boolean Functions if we have to use a 8X1 Mux ? ps: Do we use the select lines S2 S1 S0 as A,B,C and output depends solely on D or do we we take S1 & S0 as A and B respectively and S2 as an Enable? Would really appreciate a quick answer
S0, S1, S2 as A, B, C. 8 Input lines of MUX will depend on D only. You can check it by drawing a truth table or Map. Here I am just putting the results: I0 = D I1 = D I2 = D' I3 = 0 I4 = 0; I5 = D I6 = 1 I7 = 1
If we have to implement it with 8:1 MUX, then S0, S1, S2 will be connected to A, B, C. 8 Input lines of MUX will depend only on D. You can check it by drawing a truth table or Map. Here I am just putting the results: I0 = D I1 = D I2 = D' I3 = 0 I4 = 0; I5 = D I6 = 1 I7 = 1
But sir how we use this mux for output it gives only one output at one time and also output is only in the form of c and d and for output we have to know also A, B values of selected i/p
