How many 2×1 multiplexers are required to construct a 16X1 multiplexer?
Therefore, the overall combination of two 8×1 Multiplexers and one 2×1 Multiplexer performs as one 16×1 Multiplexer.
How many two input multiplexers are needed to construct a 2 10?
ISRO | ISRO CS 2008 | Question 21. How many 2-input multiplexers are required to construct a 210-input multiplexer? Explanation: Consider that we need to create 210 input multiplexer using 2-input multiplexers.
How many 2-input multiplexers are required to construct a 2 power 9 multiplexer *?
In the first level, we need to organize 29 Multiplexers which will accept 2-inputs each (hence 210 Inputs in total) & gives out 1 output each (hence 29 outputs in total).
How many multiplexers does a 16×1 multiplexer need?
In this section, let us implement 16×1 Multiplexer using 8×1 Multiplexers and 2×1 Multiplexer. We know that 8×1 Multiplexer has 8 data inputs, 3 selection lines and one output. Whereas, 16×1 Multiplexer has 16 data inputs, 4 selection lines and one output. So, we require two 8×1 Multiplexers in first stage in order to get the 16 data inputs.
Why do we need 2×1 multiplexer in second stage?
Whereas, 16×1 Multiplexer has 16 data inputs, 4 selection lines and one output. So, we require two 8×1 Multiplexers in first stage in order to get the 16 data inputs. Since, each 8×1 Multiplexer produces one output, we require a 2×1 Multiplexer in second stage by considering the outputs of first stage as inputs and to produce the final output.
Which is the output of the first stage 8×1 multiplexer?
The outputs of first stage 8×1 Multiplexers are applied as inputs of 2×1 Multiplexer that is present in second stage. The other selection line, s3 is applied to 2×1 Multiplexer. If s 3 is zero, then the output of 2×1 Multiplexer will be one of the 8 inputs Is 7 to I 0 based on the values of selection lines s 2, s 1 & s 0.
How to make an 8 MUX from a 2 mux?
Here is an example of an 8:1 MUX from 2:1 MUX without using a 2:1 MUX at the output. But, to obtain the same for a 16:1 MUX you’ll need to make a lot of modifications. Like if you draw the truth table and analyze (compare it with the above 8:1 MUX design), you’ll require two enable pins for each MUX, each with different options.
