Abstract: front page image
(EN) The present invention comprises: a signal processing device 2 that transmits, via a signal cable 4, a ΔΣ-modulated signal obtained by ΔΣ-modulating a transmission signal that is an RF signal; and a wireless device 3 that transmits, via the signal cable 4, a reception signal that is an RF signal. The signal processing device 2 transmits the ΔΣ-modulated signal to the wireless device 3. The wireless device 3 transmits the reception signal to the signal processing device 2. In the ΔΣ-modulated signal, quantization noise is suppressed at the frequency of the reception signal. The reception signal is transmitted to the signal processing device 2 while the ΔΣ-modulated signal is being transmitted to the wireless device 3.
(FR) La présente invention concerne un dispositif de traitement de signal (2) qui émet, par l'intermédiaire d'un câble de signal (4), un signal modulé en ΔΣ obtenu par modulation ΔΣ d'un signal d'émission qui est un signal RF, et un dispositif sans fil (3) qui émet, par l'intermédiaire du câble de signal (4), un signal de réception qui est un signal RF. Le dispositif de traitement de signal (2) émet le signal modulé en ΔΣ vers le dispositif sans fil (3). Le dispositif sans fil (3) émet le signal de réception vers le dispositif de traitement de signal (2). Dans le signal modulé en ΔΣ, le bruit de quantification est supprimé à la fréquence du signal de réception. Le signal de réception est émis vers le dispositif de traitement de signal (2), alors que le signal modulé en ΔΣ est émis vers le dispositif sans fil (3).
(JA) RF信号である送信信号に対してΔΣ変調されたΔΣ変調信号を、信号ケーブル4を介して、送信する信号処理装置2と、RF信号である受信信号を、信号ケーブル4を介して、送信する無線装置3と、を備え、信号処理装置2は、ΔΣ変調信号を、無線装置3へ送信し、無線装置3は、受信信号を、信号処理装置2へ送信し、前記ΔΣ変調信号は、受信信号の周波数において量子化雑音が抑圧され、受信信号は、前記ΔΣ変調信号が無線装置3へ送信されている間に、信号処理装置2へ送信される。
