NoiseAdder¶

streaming mode | Standard category

Inputs¶

signal (real) - the input signal

Outputs¶

signal (real) - the output signal with the added noise

Parameters¶

fixSeed (bool ∈ {true, false}, default = false) :
if true, 0 is used as the seed for generating random values

level (integer ∈ (-∞, 0], default = -100) :
power level of the noise generator [dB]

Description¶

This algorithm adds noise to an input signal. The average energy of the noise in dB is defined by the level parameter, and is generated using the Mersenne Twister random number generator.
