Design a BCD-to-decimal decoder. Your decoder will have 4 inputs: A, B, C and D, representing a 4-bit BCD code (A being the MSB). It will have 10 outputs: D0, D1, ..., D9, such that output Di=1 if the decimal value of the BCD input is i. The output for the undefined combinations of the BCD code should be dont cares. Provide a logic expression for each output. (A gate-level implementation is not required.)
