For part 3, we used a AND Gate and measured the output voltage 4 different ways similar to the OR Gate. Free essays, homework help, flashcards, research papers, book reports, term papers, history, science, politics Using only NAND or NOR logic gate, any other logic function can be constructed. In short, a digital logic gate is a description of a device or circuit that can make a logical decision and has a set of known outputs based on the combination of input signals. Transistors are electronic switches. Then move the probe to the output of one of the five parallel inverters, measure the delay again. There are two types of noise to be considered. A complex electronic system may have many thousands of gates. Second theorem It states that the NOR gate isequivalentto a bubbled AND gate. <> Academia.edu no longer supports Internet Explorer.

Explain the results. When one switch was connected to the power, we got a 5V output voltage. Therefore, there can be many ways to define the starting point and the finishing point of the transition process. Ans: The output of the OR gate will be high no matter what the other 2 input levels might be. When drawing a truth table, the binary values 0 and 1 are used.

To implement an OR gate using NAND gates Note: There is no lab report required for this lab. 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. OR, AND and NOT are basic gates. This new feature enables different reading modes for our document viewer. Logic gates are used to carry out the logical operations on single or multiple binary inputs and result in one binary output. A table which lists all variable inputs and corresponding output is called truth table. Combinational logic requires the use of two or more gates to form a useful, complex function. Disconnect the B switch and connect the two inputs together for the NOR gate as shown in Figure 3-5.
