The rear lights of a car are to be controlled by digital logic. There is a single lamp in each of the rear lights. The inputs are:
LT left turn switch-causes blinking of left side lamp
RT right turn switch-causes blinking of right side lamp
EM emergency flasher switch-causes blinking of both lamps
BR brake applied switch-causes both lamps to be on
BL blinking signal with 1 Hz frequency
The outputs are:
LR power control for left rear lamp
RR power control for right rear lamp
(a) Write the equations for LR and RR. Assume that BR overrides EM and that LT and RT override BR.
(b) Implement each function LR (BL, BR, EM, LT) and RR (BL, BR, EM, RT) with a 4-to-16-line decoder and external OR gates.
