    • An automatic gain control circuit is disclosed. The automatic gain control circuit receives a radio frequency signal at an input. The input passes the radio frequency signal to a first gain loop having a changeable gain. A low pass filter filters the radio frequency signal. In a second gain loop, the gain of the filtered signal is adjusted. The automatic gain control circuit includes at least one signal detector for detecting a signal level in the first gain loop and a signal level in the second gain loop. The automatic gain control circuit also includes an adjustment module for adjusting the gain of the first and second gain loops based upon the detected signal levels wherein overall gain of the first and the second gain loops is increased no greater than a predetermined value.
    • 公开了一种自动增益控制电路。 自动增益控制电路在输入端接收射频信号。 输入将射频信号传递到具有可变增益的第一增益环路。 低通滤波器对射频信号进行滤波。 在第二增益环路中,调整滤波后的信号的增益。 自动增益控制电路包括用于检测第一增益环路中的信号电平和第二增益环路中的信号电平的至少一个信号检测器。 自动增益控制电路还包括调整模块,用于根据检测到的信号电平来调整第一和第二增益环路的增益,其中第一和第二增益环路的总增益不大于预定值。

    • A network adapted to target an individual operating a microcomputer that is linked to an Internet to offer this individual goods or services appropriate to his needs that are available at a place within reach of the individual's present location. The microcomputer is provided with a GPS receiver that indicates the present location of the individual, this location and the identity of the individual being transmitted from the microcomputer to a web site on the highway. At the web site, a computer associated with a data bank storing the profiles of a multitude of consumers is programmed to find out whether the identified individual is included in the data bank, and to determine from his profile whether there are available at a place reachable from his present location appropriate goods or services. If a match is found, an offer to supply such goods or services is conveyed from the web site to the microcomputer.
