Digital logic combinational circuit

[shomikc]

Hi everyone. I came across an interesting question yesterday in a book. It requires implementing one's complement without using NOT, NAND or NOR gates. I just am wondering if that is even possible. Can you please help.

 

[wwfeldman]

this sounds like a textbook homework problem
you should figure it out for yourself

hint: what gates are available? if you examine 2 input gates, what do they do?

What gate can function as an inverter ? Hint.

Regards, Dana.

Hi everyone. Thanks for the hints. I think I have to use a 2 input XOR with one input always high. Is it correct?

You understand correctly.

Brian.

Is a transistor permitted? Invert signal polarity by common-emitter operation.

No. I get your point. But it was a 1 mark question on Digital Logic combinational circuits. A similar procedure using MOFETS is probably also possible I guess.
