Designing Combinational Circuits Write the Truth Table for the inputs and outputs. Simplify the resulting expressions for outputs (use algebra or maps). Question S. [ 2 marks ] a) A majority function has an output value of 1 if there are more 1s than Os on its inputs. The output is 0 otherwise. Design a three-input majority function. b) Find a function to detect an error in the representation of a decimal digit in BCD. In other words, write an equation with value 1 when the inputs are any one of the six unused bit combinations in BCD code, and value 0 otherwise
