Q14) An assembly line has 3 fail safe sensors and one emergency shutdown switch. The line should keep moving unless any of the following conditions arise: (i) If the emergency switch is pressed (ii) If the senorl and sensor2 are activated at the same time. (iii) If sensor 2 and sensor3 are activated at the same time. (iv) If all the sensors are activated at the same time Suppose a combinational circuit for above case is to be implemented only with NAND Gates. How many minimum number of 2 input NAND gates are required?
