ISD1420为美国ISD公司出品的优质单片语音录放电路，由振荡器、语音存储单元、前置放大器、自动增 益控制电路、抗干扰滤波器、输出放大器组成。一个最小的录放系统仅由一个麦克风、一个喇叭、两个按钮、一 个电源、少数电阻电容组成。录音内容存入永久存储单元，提供零功率信息存储，这个独一无二的方法是借助于 美国ISD公司的专利――直接模拟存储技术（DAST TM）实现的。利用它，语音和音频信号被直接存储，以其原 本的模拟形式进入EEPROM存储器。直接模拟存储允许使用一种单片固体电路方法完成其原本语音的再现。不 仅语音质量优胜，而且断电语音保护。-err

The programming port of all the FP PLC’s support OPEN MEWTOCOL-COM. This is very useful when you want to monitor PLC values/bits or to set PLC values or bits via your COMPUTER. You can use any language such as Basic, C, Pascal, Assembler or even if other suppliers of PLCs can send ASCII strings, they can talk to our PLCs to exchange data.-The programming port of all the FP PLC s support OPEN MEWTOCOL-COM.

移动电话主要采用频率复用，但分配给移动电话的频段很少，远不能满足用户的需要。 因此就提出将地区划分成小区，称为蜂窝（Cell），每个蜂窝内使用一组频率，相隔一段距离后，相同的频率又可重复使用。 -The main use of mobile phone frequency reuse, but allocated to the small-band mobile phone, far from being able to meet the needs of users. Therefore proposed to be divided into residential areas, known as cellular (Cell), each use a set of cellular frequencies, separated by some distance, the same frequency can be reused.
