An assembly line consists of 3 fail safe sensors and one emergency shutdown switch. The line must keep moving unless any of the given conditions occur:
a. When the emergency switch is pressed
b. When the senor1 and sensor2 are activated instantly.
c. When sensor 2 and sensor3 are activated instantly.
d. When all the sensors are activated instantly
Assume that a combinational circuit for above case is to be implemented merely with NAND Gates. Determine required minimum number of 2 input NAND gates.
Ans:
Number of 2-input NAND Gates required are six (6) you can try the whole implementation.
