Abstract
A narrow band interference signal removing device uses first diode arrays and second diode arrays both provided in propagation paths of surface acoustic waves in order for the first diode arrays to detect the signal magnitude of a surface acoustic wave propagating in an opposite direction to obtain information on the spectrum magnitude of an input signal and responsively control a bias to the second diode arrays.
