ABSTRACT:
A method for testing the frequency response of a communication device that when operated determines a signal-to-noise ratio for a plurality of frequency bands includes receiving a signal-to-noise ratio generated by the communication device for each of the plurality of frequency bands. The method also includes receiving the amount of noise at each of the plurality of frequency bands, and determining, for each of the plurality of frequency bands, the magnitude of the signal at each of the plurality of frequency bands based on the signal-to-noise ratio and the amount of noise at each frequency band. Thereby the frequency response of the communication device is indeed determined.
