Noise

Description

The signal generator block noise can generate different types of noise.

Mx1

Output

The output is a single dimension Mx1 noise.

Name

Name specifies the name of the block.

Sample rate

Sample rate is the sample rate of the noise.

Start

Start specifies when the noise should start. If start is above 0 s the start is zeropadded accordingly. The start can be defined in either s, ms or samples.

Length

Length specifies the length of the noise from start in either s, ms or samples.

Amplitude

Amplitude is the amplitude (Peak) of the noise. As the signal is generated on the computer the unit is defined as FS.

Type

Type is the noise type. It can either be white or pink.

Seed

Seed is a checkable option if you want to specify the random seed. Default the seed is randomized.

Outputs

Outputs specifies the number of output(s) the block will have. Each output will output the same noise with a different seed.

Examples

An example of octave analysed 1 second white and pink noise. Because the noise is only 1 second long you see a difference in the low frequencies in the pink noise.
