I'm creating a circuit with in3, in2, in1, and in0, and outputs F11-F0. The circuit has to take the input in 2s complement and output the number in binary with the sign. F11 represents the sign bit (on for negative and off for positive). So for instance, 1001 would output as -7, with F11 on and F7 on, or 0100 would output as 4, so F11 off and F4 on. Using 3-8 0-cold decoders and normal gates how would I create this. I'm also a bit lost on using decoders. I included a picture of the decoders pin configuration. enter image description here
