Increases the sampling rate by inserting zeros in between samples.

Syntax

OutputData = UpSample(InputData, Factor, Offset)

Arguments

Name

Description

InputData

Vector of data (real) to be down sampled.

Factor

Positive integer specifying the up-sampling factor.  The new sampling rate will be a multiple of this.

Offset

(Optional)

The amount by which the upsample is offset.  Must be an integer in the range 0 and Zeros – 1.

Output

Name

Description

OutputData

A vector of up-sampled data.

Example 1

Up sample a set of data by a factor of 2:

Syntax

Sampled = UpSample([1 2 3],2)

Result

Sampled = 1 0  2  0  3  0

Example 2

Repeat the above with an offset of one:

Syntax

Sampled = UpSample([1 2 3],2,1)

Result

Sampled = 0  1  0  2  0  3
