pcf8593实时时钟的驱动实例 Real Time Clock interface for Linux on CPE with FTRTC010

DFT(Discrete Fourier Transformation)是数字信号分析与处理如图形、语音及图像等领域的重要变换工具，直接计算DFT的计算量与变换区间长度N的平方成正比。当N较大时，因计算量太大，直接用DFT算法进行谱分析和信号的实时处理是不切实际的。快速傅立叶变换(Fast Fourier Transformation，简称FFT)使DFT运算效率提高1～2个数 ...

Problem D:合唱队形 Time Limit:1000MS Memory Limit:65536K Total Submit:1237 Accepted:437 Language: not limited Description N位同学站成一排，音乐老师要请其中的(N-K)位同学出列，使得剩下的K位同学排成合唱队形。 合唱队形是指这样的一种队形：设K位同学从左到右依次编号为1，2…，K，他们的身高分别为T1 ...

Problem F:汽车加油 Time Limit:1000MS Memory Limit:65536K Total Submit:1400 Accepted:404 Language: not limited Description 一辆汽车加满油后可行驶n公里。旅途中有若干个加油站。设计一个有效算法，指出应在哪些加油站停靠加油，使沿途加油次数最少。 编程任务： 对于给定的n和k(k <= 10000)个加油站位置， ...

The implementation of estimation and correction of carrier frequency offset of COFDM system in DAB receiver IC ASIC03

Fast settling-time added to the already conflicting requirements of narrow channel spacing and low phase noise lead to Fractional4 divider techniques for PLL synthesizers. We analyze discrete "beat-note spurious levels from arbitrary modulus divide sequences including those from classic accumulator ...
