What are states in logic gates?
In digital logic design only two voltage levels or states are allowed and these states are generally referred to as Logic “1” and Logic “0”, or HIGH and LOW, or TRUE and FALSE. These two states are represented in Boolean Algebra and standard truth tables by the binary digits of “1” and “0” respectively.
How many states can a logic gate have?
two
Digital devices operate on binary values so there are only two allowable digital states. Each of these states is called a Logic State. A variety of names is used to label these two states.
What are the applications of a logic gate?
Logic gates have a lot of applications but they are mainly based upon their mode of operations or their truth table. Basic logic gates are often found in circuits such as safety thermostat, push-button lock, automatic watering system, light-activated burglar alarm and many other electronic devices.
How are logic states indicated in a digital circuit?
In the context of digital circuits, these are terms that are commonly used to reflect either a zero or a one. Sometimes the logic state is indicated by the presence or absence of a voltage or different polarities of the same voltage.
What is the beginning State for Q in digital logic?
NOTE: I’m in a first year digital logic class, so the question is for theoretical use (table making, various homework problems it applies to, etc.), not actual implementation. Just for things like “if R is __ and S is __ what is Q?” Simple things like that.
Which is the combination of and NOT gate?
This basic logic gate is the combination of AND and NOT gate. This gate is the combination of OR and NOT gate. In XOR gate the output of a two-input XOR gate attains the state 1 if one adds only input attains the state 1. A. B ˉ + A ˉ. B In XNOR gate the output is in state 1 when its both inputs are the same that is, both 0 or both 1.
