PROBLEM TO BE SOLVED: To provide a method for canceling signals and its system that can quickly and reliably (stably) cancel an input signal. SOLUTION: The input signal is distributed into 1st and 2nd signals A, B, the 2nd signal B is distributed into 1st and 2nd sub signals B0, B90 that are orthogonal to each other, the amplitude of each of them is adjusted and they are recombined again as a 3rd signal B (B'), which is used to cancel the 1st signal A (A'). The amplitude of the orthogonal sub signals B0, B90 can independently be adjusted and the 3rd signal B (B') resulting from recombining the sub signals B0, B90 after the adjustment can be a cancellation signal with an optional phase and amplitude over 1st - 4th quadrants of the vector plane.
