This letter proposes, based on a bandpass sampling theory, a novel method to find available sampling ranges with a low computational complexity and high accuracy for multiple bandpass radio frequency signals. Guard-bands between downconverted signal spectrums are also taken into consideration in determining a minimum sampling frequency. We verify its validity through simulations in terms of the sampling ranges, the minimum sampling frequency, and computational efficiency.
