RESPITE: The CASA Toolkit Page: Documentation: Block Library Index:PinkNoise


PinkNoise is a signal generator block that generates a zero-mean noise signal with a sloping spectral profile such that there is approximately equal energy per octave. There are 3 controlling parameters: SAMPLE_RATE, DURATION and AMP.

SAMPLE_RATE is in units of samples per second, and DURATION is measured in seconds. The amplitude parameter, AMP, is the RMS amplitude of the signal.

Inputs Meaning Sample 1-D frame $\ge$2-D frame
No inputs

Outputs Meaning
out1 generated signal

Parameters Type Default Meaning
SAMPLE_RATE Float - Number of samples per second
DURATION Float - Duration in seconds of signal to generate
AMP Float 1.0 The RMS amplitude of the signal
