    • In one embodiment, a receiver front end circuit can receive and process multiple radio frequency (RF) signals and output downconverted signals corresponding to these signals. In turn, multiple signal processors can be coupled to this front end. Specifically, a first signal processor can receive and process the downconverted signals to output a first signal obtained from content of a first RF signal, and a second signal processor can receive and process the downconverted signals to output a second signal obtained from content of a second RF signal. In addition, the apparatus may include a detection circuit coupled to the receiver front end circuit to detect presence of at least the second signal and enable the second signal processor responsive to the detected presence.
    • 在一个实施例中,接收器前端电路可以接收和处理多个射频(RF)信号并输出​​与这些信号对应的下变频信号。 反过来,多个信号处理器可以耦合到该前端。 具体地,第一信号处理器可以接收并处理下变频信号以输出从第一RF信号的内容获得的第一信号,并且第二信号处理器可以接收并处理下变频信号以输出从第二RF信号的内容获得的第二信号 射频信号。 此外,该装置可以包括耦合到接收器前端电路的检测电路,以检测至少第二信号的存在,并使第二信号处理器能够响应于检测到的存在。
