So my first problem asks me to design an 8 to 3 priority encoder whose outputs are twos complement numbers.What I donțt get is how would I do that? since my numbers go up to 8 wouldnt that mean twos complement representation of this positive numbers would be the same as bcd?Did I misunderstood how encoders work? Another problem asks me to Build a full adder for twos complement numbers.What I did is build a full adder without the last carry out. Is that okay? Also if I have to implement full adder for Two bit numbers in Twoțs Signed Fractional how could I do that ?maybe an exemple of such an operation please..couldnțt find it on google

 

I think I got the encoder problem my bad..Simply for numbers with 1 in front I have to transform them into twos complement
