freqconv
- In digital signal processing, a digital down-converter (DDC) converts a digitized real signal centered at an intermediate frequency (IF) to a basebanded complex signal centered at zero frequency. In addition to downconversion, DDC’s typically decimat
decimation_test
- Decimation reduces the original sampling rate for a sequence to a lower rate, the opposite of interpolation. The decimation process filters the input data with a lowpass filter and then resamples the resulting smoothed signal at a lower rate.-Decimat

cic
- 在信号处理中，信号发射时，信号通过载波，调制，以电磁波的形式发射出来 在接收端，射频信号通过天线接收，超外差式等方式进行处理，变频到中频 然后通过数字技术对中频信号进行处理，此时的中频信号采样率很高，多达几十兆赫 而要解调出来的信号很小，此时就要经过滤波来得到我们需要的信号 如果直接设计滤波器，阶数会非常庞大，软件，硬件设备都承受不了 因此，一般常用的技术是进行下变频处理，其主要技术就是通过抽取滤波进行下变频 常用的滤波器就是CIC抽取, 希望可以帮助一些坛友解决基本的问

MSP430-application-of-thermometer
- 在《温度计_基本原理》程序中，已经实现了一个温度测量和显示的系统，但因为采样速率很快，且对基准源不加控制，耗电很大(800uA左右)。本例中，将温度采集速度降到1秒一次，且采样间隙时间不仅关闭基准源，还让CPU进入LPM3休眠状态，大大节省了耗电。该程序功耗仅10uA左右，可用纽扣电池长期运行(2年)。实际上对于环境温度1秒1次采样仍属浪费，如果降到5秒一次，功耗可下降到4uA左右(CR2032电池工作5年)。按KEY3后，CPU进入LPM4，功耗下降到0.1uA，这是一种常用的不断电的关机方法
