Consider the combinational circuit that is used to control a seven$-$segment LED display of a decimal digit as illustrated below, with inputs D$0,$ D$1,$ D$2,$ and D$3$ and outputs F$0,$ F$1,$ F$2,$ F$3,$ F$4,$ F$5,$ and F$6.$ The seven outputs define which segments will be activated to display a given decimal digit. The seven segments in the LED display have been labelled with the output signal that con
