2. A safety system has THREE (3) switches in the logic circuit. An alarm, T is sounds, if switch A represents OFF and switch B represents OFF; or if switch B represents ON and switch C represents OFF. A logic statement representing the scenario is as follows. T = 1, if (switch A is OFF and switch B is OFF) or (switch B is ON and switch C is OFF) a) Write a Boolean expression based on the above logic statement. b) Draw a logic circuit. c) Write a truth table for the logic circuit.
