Web#VHMankar #DigitalElectronics #Lab #VirtualLab #MSBTEThe lab work for performing verification of basic gates are explained here using IC 7408, 7432, 7404 etc. However, this is not a required step for this lab. Why are NAND gates and NOR gates sometimes referred to as. Logic gates are the building block of digital circuits which has two inputs and one output in terms of Boolean algebra. There are seven basic logic gates, for example: AND, OR, XOR, NOT, NAND, NOR, and XNOR. All seven basic logic gates have different rules for their truth table. The truth table consists of three columns- two inputs and one output. Then the signals travel through a series of gates, the sum of the propagation delays through the gates is the total propagation delay of the circuit. Power dissipation is the supplied power required to operate the desired logic function. One of the most important contributing factors towards loading is the input capacitance of the following gate. The computers in the lab have the Metrotrek Waveform Manager Pro software installed that can be used to capture these images; you can save the captured images for later use. 0000001112 00000 n Question 3: What values are you adding? - Understanding how to construct any combinational logic function using NAND or NOR gates only.

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. NAND and NOR are called universal gates as using only NAND or only TTL has a well-established popularity among logic families. Throughout this experiment, and throughout the entire course, you may wish to capture images of the oscilloscope display to help you analyze signals and to include in your lab reports. 0000004343 00000 n The AND, OR, NAND, and NOR gates can be extended to have more than two inputs.
