[0029] Since the TV programs of the TV station are transmitted in the bandwidth of about 8MHZ through COFDM, the bandwidth is much smaller than the 470MHz to 800MHz mobile phone TV band width given by the standard. figure 1 For the ordinary band-pass filter shown, considering that the mobile phone TV roams between different regions and there is no device that can be adjusted in the filter, the pass-band width of the band-pass filter must meet the standard given by the mobile phone of 470MHz to 800MHz. The width of the TV band, at this time, although the mobile phone communication signal and low-frequency noise signals can be filtered out, useless noise signals in the passband will still be introduced. if used figure 2 As shown in the filter with adjustable center frequency, because the filter has a device with adjustable physical characteristics inside, when the mobile phone TV terminal receives a TV program signal from a certain TV station, the corresponding control signal i...
