摘要
The present invention relates to an automatic bandwidth adjusting method comprising steps of receiving at least one radio signal, converting the at least one radio signal in a preset filter bandwidth into at least one audio signal; generating at least one signal-to-noise ratio (SNR) information based on the at least one audio signal, wherein the filter bandwidth is adjusted between multiple preset range intervals, and the range intervals are different; comparing the at least one SNR information with a preset first critical SNR and a preset second critical SNR to determine whether to adjust the filter bandwidth or not; outputting a bandwidth adjustment signal when the filter bandwidth needs to be adjusted; and adjusting the filter bandwidth according to the bandwidth adjustment signal.
