Therefore, we can say in conclusion that each of the three logic gates had different output voltage outcomes depending on if the switch was connected to the power or the ground. when we connected both switches to the ground the voltage was 0, where we see that <> It should be noted that the transition period for the rising and falling edges of the same gate may not necessarily be the same, although it is normally desirable to have a symmetrical transition. 8 0 obj Therefore, there can be many ways to define the starting point and the finishing point of the transition process. 0)"1 ! The results for OR Gate were different than NOT Gate. And we built circuits using multisim to prove if the output was false or true and based on the voltage output we found. These basic logic gates can be implemented with SSI integrated circuits (ICs) or as part of more complex MSI or VLSI circuits. The natural gas quality fluctuates in complex natural gas pipeline networks, because of the influence of the pipeline transmission process, changes in the gas source, and fluctuations in customer demand in the mixing process. First each of the logic gates were connected to the power and the ground one at a time. Vary the inputs of each gate and measure the output. Resistor colour coding | lab work. The basic logic gates are the basic building blocks of more complex logic circuits. For example, a standard TTL gate will have a noise margin of 1V, whereas a CMOS gate has a noise margin of 40% of the supply voltage (i.e. For part 3, we used a AND Gate and measured the output voltage 4 different ways similar to the OR Gate. Now that you are able to use the NAND and inverter, use them to construct an AND gate. The truth table of an XNOR gate is given below; Logic gates have a lot of applications, but they are mainly based upon their mode of operations or their truth table. endobj 32 0 obj <> output.
