• Aug 25, 2018 · If the truth table for a NAND gate is examined or by applying De Morgan's Laws, it can be seen that if any of the inputs are 0, then the output will be 1. However to be an OR gate, if any input is 1, the output must also be 1. Therefore, if the inputs are inverted, any high input will trigger a high output. •Fig. 11: XOR Gate Symbol. The output of an XOR gate for two boolean variables can be represented by the following truth table – The truth table of the XOR gate shows that the output is HIGH when any one, but not all of the inputs is 1 and when the both inputs are same i.e. either 0 or 1, the output is LOW. This exclusive feature eliminates a ... •When designed from truth-tables and K-maps, a full subtractor is very similar to a full adder, but it contains two inverters that a full adder does not. When configured to subtract, an adder/subtractor circuit adds a single inverter (in the form of an XOR gate) to one input of a full adder module.

    The XNOR gate is a digital logic gate that impliments logical equality - it behaves according to the truth table to the right.
