1. The gate 1.1 AND gate And gate is two inputs and one output, when both inputs are 1, the output will be 1, otherwise the output will be 0. The underlying principle of the gate is explained by relays as follows: In the case of an energized coil, there will be a magnetic effect. In the figure above we can see that if the two coils are energized, they will each suck down the switch above them, thus making the switch closed, which will then eventually lead to the bulb being energized. We can see that there is a power supply connected to the bulb, and there are two switches on this circuit, which are controlled by the other two power supplies, so three power supplies are used in the whole circuit. After simplifying the circuit, it looks like this above. As you can see, the light bulb should have the power to ignore, leaving only two switching power supplies. 1.2 Or-gate OR-gate also has two inputs and one output. If at least one of the two inputs is 1, then the output i
