<P>PROBLEM TO BE SOLVED: To properly monitor a demodulator whether or not a signal is properly demodulated. <P>SOLUTION: Monitoring of the demodulator included a step for repeating steps about each demodulation module among demodulation modules of one or more demodulators, wherein the steps include the step of receiving a first signal and a second signal from the demodulation module, the step of introducing a delay relative to the first signal and the second signal, and the step of preparing a plurality of samples by performing asynchronous sampling relating to the first signal and the second signal. Image data for representing a plurality of samples relating to the one or more demodulation modules are to be produced. The image data represents one or more mismatches of the demodulator. <P>COPYRIGHT: (C)2008,JPO&INPIT |
