Application of logic gates pdf

The two possible switch position is shown below. The truth table shows that NOT function of the switch and lamp circuit. The output of the NOT circuit will be enabled lamp lit when the input switch is open. Preparing for Competitive Exam? If Yes, then must go for this book:. It has 2 or more input signals. It produces a 1 output of any or all inputs are 1. It produces a 0 output when all inputs are 0. An OR gate corresponds to the action of parallel switches for the input.

The below table shows the four commonly used methods for expressing the OR operation. The schematics diagram shows the idea of the OR gates using switches. The lamp Y will glow when either switch A or switch B is closed. The lamp will also glow when both switches A and B are closed. The lamp will not glow when both switches A and B are open. All the possible switch combination are shown.

Switch Combination:. It produces a 1 output only when all inputs are 1. Otherwise, it produces a 0 output nothing. Motasem BM. Rebel Saffold. Anonymous P6xkcz. Decisions For Heroes. Tuan Ngoc.

The basic logic gates are used in many circuits like a push button lock, light activated burglar alarm, safety thermostat, an automatic watering system etc. Digital communication cannot happen without logic operations.

Daily life application of EOR and ENOR gate can be related to ladder switches used in homes or can be found in water level checker circuits. AND gate is used in security alarm. For Example Doorbell System 3. Now the cmos inverters are commonly used to build square wave oscillators which are used for generating clock signals. The advantage of using these is they consume low power and their interfacing is very easy compared to other logic gates.

If any one of the fan stops working, the output of the NAND gate becomes 1, which activates the alarm. A NAND gate based exhaust fan failure detection system 3.

This means that if either of these things happen, i. As the thermistor warms up its resistance decreases, the voltage across it falls and the input to the NAND gate falls. When it becomes low enough the output becomes HIGH and the buzzer sounds. If the machine lid is open or the water in the tub is below certain level or the machine is overloaded weight of water and clothes in the tub is above certain limit , the output of the corresponding sensor is set to 1, producing a 0 at the NOR gate ouput that switches the machine off.
