Sir you said that in (r-1)'s complement there is no need of borrow.but for getting 7777 we are using borrow then how can it be a simple circuit than r's complement

@alphasatari

TEJA SWAROOP that’s the explanation how we got it. But we don’t need to do this always as we know 7’s complement :7777 9’s complement. :9999 15’scomplement. : FFFF You just need to subtract from these number.

In second question is the base same?🤔

Sir how you get 10000 get plz tell me sir... when I convert it decimal to octal I got (13052)8for (5674)10

Can we get video summary or short notes of imp points with which we could revise

In 8's complement why did'nt we follow the shortcut rule,like 8888-5674?

The number 8 doesn't exist in octal number system. Its 1 through 7. Just as in binary number system digits are 0 and 1... 2 isn't included. Making 7 the highest. And 7777 - 5674 logical.

Sir if I have to find 9's complement of 469 using(r-1) method than first I have to find 8's complement and it would be (888-469)=419 and to find 9's complement I have to add 1 in it so (419+1)=420 but the answer given in book is 530??Can someone please explain which step I'M doing wrong???

9's is for decimal and 8's for octal so if you want to find the 9's complement for 469 using r-1 method you just simply subtract it from 999 so 999-469 = 530.

Can we calculate the 8's compliment of a number of 4 digit in such a way that 8888 - that number

@fragranceofphysics

No.first you have to calculate 7s complement and add one to that then you get 8s complement.for calculating 7 s complement....7777 Minus that number.

8888-5674=3214 it is not correct, can any one explain regarding as per video 6:40

sir why cant we define ( r-2) 's compliment ?? please clear my doubt

@shaikhadnan7265

4 жыл бұрын

r-1 compliment is used by computers to reduce calculations. As it totally removes the need of using carry or borrow while subtraction. Subtracting 1 to r^n makes all the digits their highest possible value in its form. Like subtracting 1 to 10^4 makes it 9999 hence no carry or borrowing is required whilr subtracting.

cool

@sagarbisht9649

3 жыл бұрын

(r-1)'s comp= r's comp -1 - N in above ex N = 1101 1's comp = 2's comp -1 -1101 -> 2's comp -1 (binary subtraction) gives 1111 so 1's comp = 1111-1101

No because the base is r=16 and by the formule you have (r-1)=15 which represents F in hexadecimal.
