6 Questions
Explain the purpose of an encoder and decoder in a block diagram and provide an example of their application.
Encoders are used to convert multiple inputs into a smaller number of outputs, while decoders perform the opposite function, converting a smaller number of inputs into a larger number of outputs. An example of their application is in digital communication systems, where encoders are used to convert analog signals into digital form and decoders are used to convert the digital signals back into analog form for transmission and reception.
What is a truth table and how is it used in digital logic design?
A truth table is a table that shows the output of a digital logic circuit for every possible combination of input values. It is used to define the behavior of the circuit and to verify its correctness.
Explain the function of a multiplexer and provide examples of 4:1, 8:1, and 16:1 multiplexer types.
A multiplexer is a digital circuit that selects one of several input signals and forwards it to a single output. Examples of multiplexer types include the 4:1 multiplexer, which selects from 4 input signals, the 8:1 multiplexer, which selects from 8 input signals, and the 16:1 multiplexer, which selects from 16 input signals.
What is the purpose of a multiplexer in a block diagram?
To select one of multiple input signals and route it to the output
What is the function of an encoder in digital logic design?
To convert multiple input signals into a coded output
What is the purpose of a truth table in digital logic design?
To define the output of a digital circuit for all possible combinations of input
