The noise in a frequency demodulated audio signal is detected on the basis of the characteristics of the stereo-multiplex signal to obtain a very reliable information that can be used for the sliding stereo-mono transition, noise blanking and a de-noising of the stereo difference signal. The system includes a processor which samples queue state information from selected intermediate nodes in the network and processes the queue state information to produce a traffic intensity map. The method may also present a second request relating to a second functionality of the computing device controlled by one or more settings of the BIOS, with the second request being selected based on the first user response.
