Abstract:
A method and a device for determining an amplitude noise and/or phase noise contained within a signal performs a quadrature mixing of the signal containing the amplitude noise and/or the phase noise into the baseband or intermediate-frequency band and an amplitude demodulation downstream of the quadrature mixing in order to determine the amplitude noise contained within the signal and a phase demodulation downstream of the quadrature mixing in order to determine the phase noise contained within the signal.
