How many OR gates are required for the construction of a 4-to-1 multiplexer?
How many OR 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 many 4-to-1 multiplexers should be used to make a 64 to 1 multiplexer and show the circuit?
Hence, total number of 4 : 1 MUX are required to implement 64 : 1 MUX = 16 + 4 + 1 = 21.
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 |
How do you create a 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.
What is a demultiplexer Mcq?
A demultiplexer (or demux) is a device that takes a single input line and routes it to one of several digital output lines. It consists of 2n outputs and has n selection lines, which are used to select which output line to send the input. It is also called as a data distributor.
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 do muxes work?
A multiplexer is a system of multiple inputs and just one output to receive signals coming from multiple acquisition networks. The device transfers all input signals to a microprocessor, which receives and processes the data, transmits it to the output devices, and controls the system as a whole.
What is multiplexer in 4 to 1 MUX?
VHDL 4 to 1 Mux (Multiplexer) Multiplexer. Multiplexer (MUX) select one input from the multiple inputs and forwarded to output line through selection line. It consist of 2 power n input and 1 output. The input data lines are controlled by n selection lines.
How many selection lines are there in a 4 to 1 multiplexer?
Four-to-One Multiplexer In 4:1 MUX, there will be 4 input lines and 1 output line. And to control which input should be selected out of these 4, we need 2 selection lines. Thus, it is evident from the diagram below that D0, D1, D2 and D3 are the input lines and A, B are the two selection lines.
How to select a single input in a multiplexer?
A multiplexer can be designed with various inputs according to our needs. If we have four inputs and we want to select a single one then we can use four-to-one (4:1) MUX.
What is the output of the multiplexer when S 0 =0?
According to the truth table, the output of the multiplexer fully depends on selection lines (binary data , 00,01,10 & 11) and one input would be selected from all the input data lines as the output. When S 0 =0 and S 1 =0 , then A 0 would be the output.
