What is the output of 4 1 multiplexer?

What is the output of 4 1 multiplexer?

4×1 Multiplexer has four data inputs I3, I2, I1 & I0, two selection lines s1 & s0 and one output Y. The block diagram of 4×1 Multiplexer is shown in the following figure. One of these 4 inputs will be connected to the output based on the combination of inputs present at these two selection lines.

How many OR gates are required for the construction of a 4-to-1 multiplexer?

12. How many NOT gates 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 may inverters are needed to implement 4 1 multiplexer?

At first stage: 4 multiplexers are needed for 16 inputs, At second stage: the output of these 4 multiplexers is connected to inputs of 1 multiplexer. Total 4 × 1 multiplexers needed are 4 + 1 = 5….Detailed Solution.

Given Multiplexer To be implemented Required
8 x 1 64 x 1 8 + 1 = 9

What are the four basic types of multiplexing?

Types of Multiplexing Techniques

  • Frequency Division Multiplexing (FDM)
  • Wavelength Division Multiplexing (WDM)
  • Time Division Multiplexing (TDM)

Which gates are used in multiplexer?

All the standard logic gates can be implemented with multiplexers. It is NOT Gate using 2:1 MUX. The implementation of NOT gate is done using “n” selection lines.

How many NAND gates make a full subtractor?

2 Half Subtractors and an OR gate is required to implement a Full Subtractor.

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.
