if you are confused about 7th and 10th row of T.T , read this: In 7th row A1=0,Ao=1 B1=1, Bo=0 , after converting these to decimal ,its clear that A1Ao = 1 and B1Bo=2 and clearly 1
At 4:40 remember this shortcut. Pair 2-2 variable and apply ex-nor and if same kind of 1 are there if another diagonal (we know there are 2 diagonals) Then replace ex-nor by ex-or
do not compare them as bits (0,1) see them as binary numbers like 00 = 0 || 01=1 || 10=2 || 11=3. and then compare them using mathematical logic hope it helped
In the case of A=B (4:00) we get check board configuration right???? In that case we use xor operator if the 1 is present in odd ones ..shells.....and we get expression as Ao xor A1 xor B1 xor Bo In the same way for the above case why don't u choose Ao xnor A1 xnor Bo xnor B1.
Hello, I think there is a mistake in one of the Expressions. Please look at the last one. I think that is the wright Expression A>B = A° & !B' & !B° + A' & A° & !B° + A' & !B & B°

There is a mistake in the k-map reduction for A>B
The reduced expression from kmap would be (A0 B1' B0')+(A1 B1')+(A1 A0 B0')

No need of converting in decimal .

Saved my lab prep, thank you!!
you can group the 1's in the upper left corner and lower botton corner at A
@Neso Academy
Could you review the table? It seems part of it has been wrongly filled.
Thanks
I thought so too. But it is correct. You were missing the fact that A1; B1 are MSB and A0; B0 are LSB of the 2 bit words A and B respectively.
do not compare them as bits (0,1) see them as binary numbers like 00 = 0 || 01=1 || 10=2 || 11=3. and then compare them using mathematical logic hope it helped

for 6 bits of ab should be 0,1,0
and for 7 also
Sir, for A= B logical expression A XOR B XOR C XOR D.
Is not right?
for A=B isn't it the checkboard configuration??... hence it will be the ex-OR of the inputs.. plz let me know

No bruh ... 10>01
There's a mistake,there is not 1 in 6th place of truth table from 0, that results in false k map.
expression for A>B is wrong.It will be A0.B1bar.Bobar instead of A0.B1 bar.B0

hello sir...do you have any plans for 4 bit comparator... i mean how should i do the truth table??
mentally think binary in decimal and make the truth table ..👍👍
Sir please verify the A
Sir could you pls upload the 4 bit comparator
4 bit comparator means 256 combinations how can he implement 😅
@@HarshSharma-mu2yh 255*
it is not clear to me, what is the symbol used for XNOR when writing the function?
Can for 2nd case, A=B, can A0'B0' not be a case? Since the value of A0=0 and B0=0 is the same and does not change across the diagnoal?
K map for (A=B) and (A>B) is incorrect, (1001) (0110) (a1 a0 b1 b0) for A=B are missing and ( 1111) (a1 a0 b1 b0) for A>B. Cheers.
in the 7th row why A
01 is 1 AND 10 is 2. 1
The pair bits are converted into decimal and then compared.
Tanx a lot. I was confused for long time.
You are carrying whole Indian engineering college:s students
in the a=b u said its (a xnor b) but u didnt draw the line above the experssion ... it looks like its (a xor b)

so what ?
Sir s.l.no.11 having input same means equal A=B will come.then howin kmap it's 1 will come in A less than B.
sir why we are not use Check Board Configuration in Case of A=B?
I'm sorry. There is a mistake in the outputs for input 0110. It should be 010 for the outputs where A=B.
No, it's not a mistake, the 0110 is actually A= 01 & B= 10 .... A1=0, A0=1, B1= 1, B0= 0 ===> A = 01 = 1 in decimal & B = 10 = 2 in decimal ===> A
sir there is a mistake in truth table.The wrong is in output of 6th row( 0110).
if it is, is it in the 9th row incorrect too?
Sir there is a mistake in your A>B expression pls correct it thank you
Sir there is a mistake in 0110 line
And 1001 line please correct it sir ?????
You have done a mistake in 0110 line
0 1 1 0
0 1 is for A and after conversion to decimal ,we get A= 1
1 0 is for B and after conversion to decimal ,we get B= 2
Therefore A
