Hello there,
Here is a circuit challenge if you feel up to the task.
We have three inputs A,B,C, and three outputs which must be the invert of the three inputs, so the outputs would be A', B', C'. Normally we would just hook up three inverters, one inverter for each line, so that the three inputs get inverted, and we are done.
But this challenge requires that you can only use two inverters and any number of AND and OR gates, but NOTHING else. The three outputs must be the inputs inverted.
To illustrate the more typical circuit with three inverters:
A---|>o---A'
B---|>o---B'
C---|>o---C'
That circuit uses three inverters as shown, but the challenge circuit can only use two and also any number of AND and OR gates.
To answer any possible question about NAND and NOR gates, the answer is "NO", you can not use any NAND or NOR or XOR or anything else, just AND and OR are allowed (along with the two inverters).
Also, no time multiplexing allowed either, it has to be a standard combinatorial logic circuit.
