...In a wireless transmitter, signal components that appear outside the output signal of the frequency band theoretically determined by the specified modulation signal and modulation method. When these are radiated into space through the transmitter itself or an antenna, they are called spurious radiation. In addition, normal receivers can sometimes receive signals other than the specified receiving signal, and the sensitivity of such reception is called spurious sensitivity or spurious response, and the lower this is, the less susceptible it is to interference. *Some terminology that mentions "spurious radiation" is listed below.

…無線送信機において,所定の変調信号と変調方法により理論的に定められる周波数帯域の出力信号以外に出てくる信号成分。これが送信機自身または空中線などを通じて空間に放射されたものを不要放射spurious radiationという。また,通常の受信機においては所定の受信信号以外の信号に対しても受信できる場合があり,その受信の感度をスプリアス感度,またはスプリアス応答spurious responseといい,これが低いほうが妨害を受けにくい。… ※「spurious radiation」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
