Made Easy Test Series
Please help me! BCD number here given are positive(0 -9) and we know that the 9’s complement of a positive number is that number itself. Then why they have subtracted each BCD number from 9? And suppose if I take the 9’s complement of a number for instance “7” that would be 2. Doesn't it means that 2 represent a negative number that is -7?

Made easy Test Series, Digital Logic, Counters
Hello, I have a doubt here. It is given that we have a cascaded counter with : Counter C1 as Mod 2 counter and C2 as Mod 3 counter. Therefore I can assume that C1 uses 1 flip-flop and C2 uses 2 flipflops. Now assuming the ... the solution (it is given 1000 KHz). Can anyone explain me the given solution? How they have arrived at the equation? Thanks!
