特别是在高频接收机中的信号处理方法以及信号调节电路
摘要：
在用于信号调节的方法中，设置有具有放大器(64)的第一信号路径(6)和具有增益系数可控的放大器(74)的第二信号路径(7)。信号被施加到第一和第二信号路径(6，7)上并在第一信号路径(6)上被放大和解调。同时，该信号在第二信号路径(7)上以增益系数被放大，并且由第二信号路径放大的信号的功率被确定。该功率被用于确定增益系数。因此信号调节电路包含第一和第二信号路径(6，7)以及第一和第二操作状态。在第一操作状态中，第一信号路径(6)被配置用于放大以便进行解调，以及第二信号路径(7)被配置用于放大以便确定存在的信号的功率。在第二操作状态中，两个信号路径之一是未激活的，而另一个路径被配置用于对存在的信号进行解调。
摘要（英）：

A first signal path having an amplifier and a second signal path having an amplifier with adjustable gain factor are provided. A signal applied to the first and second signal paths is amplified and demodulated on the first signal path. Concurrently, the signal is amplified on the second signal path with a gain factor, and a power of the signal amplified by the second signal path is determined and used for determining the gain factor. A signal conditioning circuit has first and second signal paths and a first and a second operating state. In the first operating state, the first signal path is arranged for amplification for a demodulation, and the second signal path is arranged for amplification for determination of a power of the signal present. In the second operating state, one of the two signal paths is inactive and the other is arranged for demodulating the signal present.
