Abstract: A multi-channel processing system and a band pass filtering method thereof are provided to selectively generate a channel by varying a filter coefficient of a band pass filter through a controller, thereby offering a simple-structured and efficient multi-channel processing system with only one band pass filter irrespective of the number of channels to be generated. A channel selection input unit(300) inputs a channel select signal which contains on/off information of each channel(FA: Frequency Assignment). A controller(210) stores data which includes the number of filter coefficients, the number of overall receiving channels(FAs) of a system, baseband filter coefficients, intervals among the channels(FAs), and central/sampling frequencies of the channels(FAs), then generates a filter coefficient corresponding to the channel select signal by using the data. A band pass filter(240) varies preset filter coefficients according to the filter coefficient, and filters a channel to be filtered from an input signal.
