PROBLEM TO BE SOLVED: To provide multi-mode radio equipment in which characteristics of filtering for reception band limitation is easily changed. SOLUTION: An analog-digital converting means 21 converts a received signal from an analog signal to a digital signal, detecting means 22, 23, 24a, and 24b detect the received signal converted into the digital signal, and a digital signal processing means 27 performs, through digital signal processing, filtering processing for limiting the band of the signal to limit the band of the signal as the detection result, and demodulates the signal through digital signal processing; and filtering characteristic determining data supplying means 6, 52, and 28 supply data determining filtering characteristics to the digital signal processing means 27, which performs the filtering processing for filtering characteristics determined by the supplied data.
