A car has three controls, an accelerator (A), a brake (B) and a Cruise control (C). An embedded system is to be developed to activate a warning light, as follows: If the brake control and the accelerator control are used together the warning light should be red. The warning light should also be red if the accelerator control is used whilst the cruise control is activated. In all other cases the warning light is green. i. Complete this truth table where a 1 in the result column indicates that the warning light is red, and a 0 indicates that the warning light is green. Table 1 A 0 0 0 0 1 1 1 1 B 0 O 1 1 0 0 1 1 C O 1 0 1 0 1 0 1 Result (Red warning light = 1) (Green warning light = 0) A different warning system is to be used for controls D, E and F. Table 2 shows a truth table indicating whether a red light or a green light should be activated for this new warning system: Table 2 D E 0 0 0 0 1 1 1 1 0 0 1 1 0 0 1 1 F LL 0 1 0 1 0 1 0 1 Result (Red warning light = 1) (Green warning light = 0) 0 0 0 1 0 0 1 0 1 ii. Using the method write a logic expression using D, E and F, that could be used to build a logic circuit for the truth table in Table 2.
