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.
