摘要： A pulse sample demodulator which has a first sample and hold circuit detects the peak amplitude of the time varying waveform during a short sampling interval. The first sample and hold circuit is triggered by narrow pulses produced by a circuit responsive to the occurrence of each peak in the time varying waveform. A second sample and hold circuit, sampling during an interval not coincident with the first sampling interval, receives the information stored in the first sample and hold circuit; but sampling at a different interval, it does not receive the time varying signal applied to the first sample and hold circuit, which would otherwise appear as ripple in the output of the demodulator.

摘要： A cellular telecommunications system having a security feature which allows only pre-authorized users no complete cellular telephone calls. The system and method recognizes a cellular radiotelephone's pre-programmed a pre-selected telephone number and a automated number identification code (ANI). The pre-selected telephone number is reserved to the pre-paid cellular telecommunications system. The cellular radiotelephone transmits the ANI and a dialed number identification system code (DNIS) to a cellular switch, which contacts a host computer for call validation the pre-paid service provider.
摘要翻译：具有安全特征的蜂窝电信系统，其仅允许预授权用户没有完整的蜂窝电话呼叫。该系统和方法识别蜂窝无线电话机预编程的预选电话号码和自动号码识别码（ANI）。预先选择的电话号码预留给预付费蜂窝电信系统。蜂窝无线电话机将ANI和拨号号码识别系统码（DNIS）发送到蜂窝交换机，蜂窝交换机与主计算机联系以进行预付费服务提供商的呼叫验证。
