Sigma调制功能，便可提高其频率精度，大幅降低相位噪音及带内杂散信号，并???持极高的切换速度。系统设计工程师可以利用 Delta Sigma PLL将比较频率提高到很高的水平，以大大降低相位噪音。但高比较频率会导致产生周期滑动(cycle slipping)现象。-Sigma modulation function, can increase its frequency accuracy, dramatically reducing the in-band phase noise and spurious signals, and??? Holders of high switching speed. System design engineers can take advantage of Delta Sigma PLL compares the frequency increased to a very high level in order to significantly reduce the phase noise. However, the high comparison frequency would result in sliding cycle (cycle slipping) phenomenon.

LDPC编码，BPSK调制，AWGN信道，译码，可以仿真出误码率曲线

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
