Question
Consider a digital logic circuit that has three inputs, A, B, and C, and the output of the digital circuit is LOW only when a majority of the inputs are HIGH. Note that HIGH represents that the output is 1, and LOW represents that the output is 0.
a) Interpret the problem to set up a truth table to describe its operation, relating the inputs and the outputs of the circuit.
b) Based on the truth table, write the standard sum-of-product (SOP) expression for the output function
c) Implement the logic circuit (sketch the logic circuit diagram) for the final simplified SOP expression using logic gates

- Design a code converter that converts an unsigned number a into its negative 2's complement representation -a. Specifically, the circuit has two inputs: a1 and ao, and three outputs: b1 and bo (the equivalent to -a) and valid, which is 1 when -a can be represented in 2's complement and O otherwise. 1. Write the truth table for the code converter. 2.
