Consider that we need to create 210 input multiplexer using 2-input multiplexers. 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 2x multiplexers are needed for construction?
To implement 2n × 1 MUX using 2 × 1 MUX, the total number of 2 × 1 MUX required is (2n – 1). The sum will give the total number of MUX required to implement 16 × 1 multiplexer using 2 × 1, i.e….4.6.
| Given MUX | To be implemented | Required |
|---|---|---|
| 8 : 1 | 64 : 1 | 8 + 1 = 9 |
| 8 : 1 | 256 : 1 | 32 + 4 + 1 = 37 |
How many 2×1 MUXS are needed for 8×1 mux?
Therefore, the overall combination of two 4×1 Multiplexers and one 2×1 Multiplexer performs as one 8×1 Multiplexer.
What is the minimum number of 2 to 1 multiplexers needed if we want to build 10 to 1 multiplexer from 2 to 1 multiplexers only?
We need to implement 4 to 1 Mux using 2 to 1 Mux.
How many2 1 multiplexer are required to generated 2 N 1 multiplexer?
Each of the 2-input muxes reduces the number of signals by 1, thereby requiring total of “7” 2-input muxes to implement an 8-input mux. Let us consider a circuit with 8 inputs and variable outputs.
How many 2x MUXs are needed?
Implementation of NAND, NOR, XOR and XNOR gates requires two 2:1 Mux. First multiplexer will act as NOT gate which will provide complemented input to the second multiplexer. Three(3) 2 : 1 MUX are required to implement 4 : 1 MUX.
How many not gates are required for the construction of a 8 to 1 multiplexer?
From the above Boolean equation, the logic circuit diagram of an 8-to-1 multiplexer can be implemented by using 8 AND gates, 1 OR gate and 7 NOT gates as shown in below figure.
How many and gates are needed for 2 to 1 mux?
Implementation of NAND, NOR, XOR and XNOR gates requires two 2:1 Mux. First multiplexer will act as NOT gate which will provide complemented input to the second multiplexer.
What are the minimum number of 2 1 multiplexers required to generate a 2 input AND gate and a 2 input EX OR gate * 1 point?
What are the minimum number of 2 1 mux required to generate a 2 input AND gate and a 2 input EX OR gates? ans is A . answer will be 1 mux for AND and 2 mux for exor.
