If several lines are simultaneously high, the circuit encodes the highest number. If all the input lines are low, the circuit codes AB = 00, but Eout = 1 is signaled that this code is not validated. In all other cases Eout = 0. - The operation described so far is observed when Ein = 1. If Ein = 0, we have: A = B = Eout = 0. 1- Give the encoder truth table. 2- Give the logical expressions of outputs A, B and Eout as a function of the inputs of EO... E3 and Ein. & 3- Deduce the logic circuit of the encoder.
