摘要:
An apparatus and method for generation of a noise signal are provided. The apparatus includes a noise synthesizing module and a noise signal transfer module. The noise synthesizing module includes a voltage controlled oscillator, a phase frequency detector, a phase locked loop filter, and a reference generator which form a phase locked loop. An output signal of the reference generator is provided to a first phase-frequency input of the phase-frequency detector, and an output signal of the voltage controlled oscillator is provided to a second input of the phase-frequency detector. An output signal of the phase-frequency detector is provided to an input of the phase locked loop filter, and an output of the phase locked loop filter is provided to a frequency control input of the voltage controlled oscillator. The noise signal transfer module includes a sinusoidal generator and a frequency mixer having a first input which is provided with an output signal of the phase frequency detector and a second input which is provided with an output signal of the sinusoidal.
