Question

The minimum number of selection inputs requred for selecting on out of 32 input are

Answer 1

Answer:

Explanation:

When you set the Mode parameter to Value, the block computes the minimum value in each row, column, entire input, or over a specified dimension. The block outputs each element as the minimum value in the corresponding column, row, vector, or entire input. The output depends on the setting of the Find the minimum value over parameter. For example, consider a 3-dimensional input signal of size M-by-N-by-P:

Each row — The output at each sample time consists of an M-by-1-by-P array, where each element contains the minimum value of each vector over the second dimension of the input. For an M-by-N input matrix, the block outputs an M-by-1 column vector at each sample time.

Each column — The output at each sample time consists of a 1-by-N-by-P array, where each element contains the minimum value of each vector over the first dimension of the input. For an M-by-N input matrix, the block outputs a 1-by-N row vector at each sample time.

In this mode, the block treats length-M unoriented vector inputs as M-by-1 column vectors.

Entire input — The output at each sample time is a scalar that contains the minimum value in the M-by-N-by-P input matrix.

Specified dimension — The output at each sample time depends on Dimension. When you set Dimension to 1, the block output is the same as when you select Each column. When you set Dimension to 2, the block output is the same as when you select Each row. When you set Dimension to 3, the block outputs an M-by-N matrix containing the minimum value of each vector over the third dimension of the input, at each sample time.

For complex inputs, the block selects the value in each row or column of the input, along vectors of a specified dimension of the input, or of the entire input that has the minimum magnitude squared as shown below. For complex value u=a+bi, the magnitude squared is a

Answer 2

Answer:

minimum number of selection inputs required will be 5

Explanation:

It is given that there is 32 input lines.

So, for a multiplexer if there are 32 input lines then, the number of selecting one line will be [log₂(n)]

here, n = 32

which means number of select lines will be log₂(32) = 5

Therefore the minimum number of selection inputs required will be 5

Multiplexer :

• In electronic devices, a multiplexer is defined as a data selector, which selects the data between numerous number of analog ands digital input signals and them it forwards the selected input signal to a single output signal line.

• These signal input lines are separate by some digital lines known as selection lines.

• It is also called "mux" sometimes.
• In simple form it is also known as many into one.
