 K Maps are not allowed. (20 points) A seven-segment display decoder

K Maps are not allowed.

(20 points) A seven-segment display decoder takes a 4-bit data input D3:0 and produces seven outputs to control light-emitting diodes to display a digit from 0 to 9 . The seven outputs are often called segments a through g, or SaSg, as defined in the following figure (a). The digits are shown in figure (b). Write a true table for the outputs, then use Boolean identities to find the simplified Boolean functions for outputs Sa and Sb. Assume that illegal input values (10-15) produce a blank readout. (a) Seven-segment display decoder icon (b) Seven-segment display digits
