Abstract: An antenna switching apparatus which detects an antenna of good reception with high precision and suppresses control errors in antenna switching. A comparator compares a noise component obtained from a selected antenna with a threshold for noise detection. When noise detection occurs a predetermined number of times within a predetermined time, an antenna switching control unit outputs an antenna switching control signal to switch to another antenna. If all antennas are switched within a predetermined time, a noise switching count analyzing unit outputs a sensitivity control signal, deciding that the threshold should be changed. A noise detection sensitivity setting unit, when supplied with the sensitivity control signal within a predetermined time, increases the threshold to lower the noise detection sensitivity of the comparator.

Abstract: A receiver which selectively switches an antenna which provides a reception signal with a good signal usability. The receiver cuts off a noise detecting filter during a predetermined cut-off period after an antenna has been selectively switched by a switching circuit. The presence/absence of a noise component delivered by the noise detecting filter is determined in accordance with the logic value of binary data delivered by a comparator. The presence/absence of the noise component is thus determined after the predetermined period. This allows for preventing the effect of an impulse noise irrespective of the impulse noise produced when the antenna selectively switched provides a reception signal with a good signal usability, thereby making it possible to use the selected antenna for providing a reception signal with a good signal usability. Thus, it is possible to prevent improper control on the switching of antennas.
