Hence, we need
three 2 to
1Multiplexers to implement 4 to 1 Mux.
How many select inputs does an 4 to 1 multiplexer require?
A 4-to-1 multiplexer consists
four data
input lines as D0 to D3, two select lines as S0 and S1 and a single output line Y. The select lines S0 and S1 select one of the four input lines to connect the output line.
How many and gates are required for the construction of a 4 to 1 multiplexer?
4 x 1 mux need
4 AND and 1 OR and 2 NOT gates
. Replace OR gate with Invert-input NAND , then above circuit will be replace with 2 NOT and 5 NAND , then 2 NANDS for 2 NOT’s , then total 7 NAND gates required.
How may inverters are needed to implement 4 1 multiplexer?
| Given Multiplexer To be implemented Required | 8 x 1 64 x 1 8 + 1 = 9 |
|---|
What are the minimum number of 2 to 1 multiplexers required to Realise a 4 to 1 multiplexer is?
Three
(3) 2 : 1 MUX are required to implement 4 : 1 MUX.
What is the minimum number of 2 to 1 multiplexers required to generate a 2 input AND gate?
We need to implement
4 to 1 Mux
using 2 to 1 Mux.
How many 1 to 4 Line demux are required to construct a 1 to 64 line Demux?
of select lines. Therefore, for 1:4 demultiplexer,
2 select lines
are required. Explanation: A demultiplexer sends a single input to multiple outputs, depending on the select lines.
What is the final output of a multiplexer?
Multiplexer is a combinational circuit that has maximum of 2
n
data inputs, ‘n’ selection lines and
single output line
. One of these data inputs will be connected to the output based on the values of selection lines.
Which device has a one input and many output?
A Demultiplexer or Demux
is a device that takes a single input line and routes it to one of several digital output lines. It is a process of taking information from one input and transmitting over one of many outputs. It is the opposite of multiplexer.
How many 4 1 MUXS are required to develop a 16 1 mux only?
The basis: See it this way: You need a combinational logic with 16 input pins, 4 select lines and one output. In a 4:1 mux, you have 4 input pins, two select lines and one output. So, at the least you have to use
4 4:1 MUX
, to obtain 16 input lines.
Are called universal gate?
NAND and NOR gates
are called universal gates because they perform all the Logic functions OR, AND and NOT.
How many and gates are required for a 1 to 8 multiplexer?
For a 1 to 8 multiplexer a total
of 8 AND gates
are required.
How many not kids are required for the construction of a 4-to-1 multiplexer?
Explanation: there are
two not
gates required for the construction of 4-to-1 multiplexer.
How do you solve MUX problems?
- Firstly truth table is constructed for the given multiplexer.
- Select lines in multiplexer are considered as input for the truth table.
- Output in truth table can be four forms i.e. ( 0, 1, Q, Q’).
- Now with the help of truth table we find the extended expression.
How many select line are required for a 1 to 8 demultiplexer?
Step-by-step explanation:
A 1 to 8 demultiplexer consists of
one input line, 8 output lines and 3 select lines
. Let the input be D, S1 and S2 are two select lines and eight outputs from Y0 to Y7. It is also called as 3 to 8 demux because of the 3 selection lines.
What is a multiplexer Sanfoundry?
A multiplexer (or MUX) is
a device that selects one of several analog or digital input signals and forwards the selected input into a single line
, depending on the active select lines.
