Hello, During the last classes we worked on 7447, 74185 converters and displaying DEC/BIN numbers. I`m stuck with my homework right now. Build a logical gate function with NOR (2 inputs) and OR (2 inputs) gates only which realize following task: 1 0 0 1 0 1 1 0 0 1 0 0 1 1 1 1 Inputs: 4 switches SW Outputs: 2 7-segments displays which show decimal entered number + one 7-segment display which show actual output state (0 or 1). For displaying decimal numbers I have to use 74185 and 7447 modules, for displaying 0 or 1 - 7447 only. I made truth table, K-maps, and schema But I have no access to FPGA Cyclone II on which we work and I can`t figure out how to replace all this gates with 3 converters and two gates only. Could anyone give me any suggestions? Sorry for my English. Thank You.
