Abstract
The present invention discloses a wireless signal receiving device and method capable of receiving three or more signals of different central frequencies. An embodiment of said device comprises: a receiving circuit operable to generate a reception signal according to a wireless signal including a first, second, and third wireless signals of different central frequencies; a mixer operable to generate a mixing signal by processing the reception signal according to an oscillation clock in which the mixing signal includes a first, second and third intermediate-frequency (IF) signals and the central frequency of the third IF signal is higher than the other two; and a digital signal generating circuit operable to generate a first, second and third digital signals by processing the first, second and third IF signals according to a sampling frequency in which the sampling frequency is lower than two times the maximum frequency of the third IF signal.
