2 cards from this section. Quick, good the night before a test.
What is the output of an XNOR gate when both inputs are 1?
Think about when the inputs match.
List the two combinations of inputs that output a 1 in an XNOR gate.
Remember: it outputs high when both inputs are the same.
What is the output of a CMOS XNOR gate with inputs 0 and 1?
Recall the definition of XNOR.
True or False: The XNOR gate outputs true only when both inputs are different.
Think about the gate's behavior.
Create a diagram of a circuit that uses several XNOR gates to check two bits and provide a parity output. Indicate all inputs and outputs clearly.
Think about how outputs could cascade through logic gates.
Given a sequence of bits, apply an XNOR operation to them step-by-step to find if there’s an even or odd parity.
Use a systematic approach to keep track of the current parity state.
