What is the role of select lines in a multiplexer?
select lines, which are used to select which input line to send to the output. A multiplexer makes it possible for several input signals to share one device or resource, for example, one analog-to-digital converter or one communications transmission medium, instead of having one device per input signal.
What is the relation between input and select lines in case of a multiplexer?
Generally, the selection of each input line in a multiplexer is controlled by an additional set of inputs called control lines and according to the binary condition of these control inputs, either “HIGH” or “LOW” the appropriate data input is connected directly to the output.
What is a selection line?
A select line selects something, like a specific chip. A control line is a line that controls something. A select line is a form of control line, along with such things as read, write, etc.
What is relationship between no of select lines and no of outputs in Demux?
A demultiplexer (also known as a demux or data distributor) is defined as a circuit that can distribute or deliver multiple outputs from a single input. A demultiplexer can perform as a single input with many output switches. The demultiplexer’s output lines are ‘n’ in number, the select line number is ‘m’ and n = 2m.
What piece of computer hardware uses logic gates?
Logic gates are pieces of hardware that perform operations on boolean inputs, allowing us to create complex devices out of abstract boolean algebra. Logic gates are the fundamental building blocks of hardware and processors will be made out of billions of them….XOR ( )
| A | B | A ⊕ B {\displaystyle ~A\oplus B} |
|---|---|---|
| 1 | 0 | 1 |
| 1 | 1 | 0 |
How many select lines does a multiplexer with 8 data inputs have?
3 select lines
8 to 1 Multiplexer Circuit Diagram An 8-to-1 multiplexer is a digital multiplexer that has 8 data inputs, 3 select lines, and one output. To implement an 8-to-1 multiplexer circuit we need 8 AND gates, an OR gate, and a 3 NOT gate.
What is the role of multiplexer when enable input is high Mcq?
What is the function of an enable input on a multiplexer chip? Explanation: Enable input is used to active the chip, when enable is high the chip works (ACTIVE), when enable is low the chip does not work (MEMORY).
