The rear lights of a car are to be controlled by digital logic. There is a single lamp in each of the rear lights.

Inputs

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

Outputs

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.
