本発明はＦＭ放送受信機に関し、特に複数のＦＭ放送を
高忠実度に受信するＦＭ放送受信機に関する。Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an FM broadcast receiver, and particularly to an FM broadcast receiver that receives a plurality of FM broadcasts with high fidelity.
従来、この種のＦＭ放送受信機は、受信アンテナの入力

る。Conventionally, this type of FM broadcast receiver has two types of receiving antenna input terminals: one that can only support one receiving antenna input terminal, and one that can accommodate two or more receiving antenna input terminals. Generally, the configuration is such that switching between stations and receiving antennas can be selected independently.

。また、この場合、受信アンテナを回転させて電波の到
来する向きに合わせる方法もあるが、扱いにくいという
欠点がある。When the conventional FM broadcast receiver described above is equipped with one receiving antenna, when receiving and demodulating FM broadcast radio waves arriving from different directions, the receiving antenna is used for receiving radio waves from either one. If the directions of the signals do not match, a sufficient reception level cannot be obtained. The disadvantage is that it is not possible to create high-fidelity digital tones due to multipath or multi-pass. In this case, there is also a method of rotating the receiving antenna to match the direction in which the radio waves arrive, but this method has the drawback of being difficult to handle.

Even when equipped with two or more antennas, it is necessary to manually switch the receiving antenna according to the selected station], and if you want to receive the desired broadcasting station with high fidelity, you will have to perform double operations. The disadvantage is that the operation is complicated.
