Abstract:
     A method for convering group signals in different frequency system and its devices, wherein the converting circuit mainly includes a plurality of phase generators that contain the first inputting pulse signals, a plurality of signal pick-up devices corresponding to these phase generators, a plurality of converters corresponding to these signal pick-up devices, the inputs of these converters receive the second inputting pulse signals, the others are connected to the outputs of the corresponding signal pickup devices; a signal combining device whose inputs are respectively connected to the converters; its method is that decomposing the group signals based on the first inputting pulse signals into a plurality of non-group signals by the signals pickup devices cooperated with the phase generators.
