<p>The present invention relates to a method for demodulating a wideband frequency comprising the steps of: down-converting a radio frequency (RF) modulation signal where a mixer is received into a frequency band where a signal process is possible; converting, by an analog to digital converter (ADC), the down-converted RF modulation signal into a digital signal; determining, by a control portion, whether a signal having an intensity greater than or equal to a preset threshold among digital signals converted through the ADC exists or not; extracting, by the control portion, a frequency of the signal having the intensity greater than or equal to the threshold; and demodulating, by the control portion, a signal corresponding to a preset standard frequency band with respect to the extracted frequency.</p> |
