4种不同模型的程序 对雷达杂波方针很有用的

本例载波频率为20KHz，或载波周期为50μs。DSP晶振10MHz，内部4倍频，时钟频率为40MHz，计数周期为25ns。假设调制波频率由外部输入（1～50Hz），并转换成合适的格式（本例为Q4格式）。调制系数M为0～0.9。死区时间1.6μs。最小删除脉宽3μs。 主程序的工作是根据输入的调制波频率计算N、2N和M值。 -Example for the carrier frequency 20KHz, or carrier period is 50μs. DSP crystal 10MHz, internal 4 multiplier, the clock frequency of 40MHz, counting cycle 25ns. Assuming wave frequency modulation by external input (1 ~ 50Hz), and converted into an appropriate format (in this case for Q4 format). Modulation coefficient M is 0 ~ 0.9. Dead time 1.6μs. Delete the smallest pulse width 3μs. The work of the main program is based on input frequency modulation wave calculation of N, 2N and M values.

输入三个整数x,y,z，请把这三个数由小到大输出。 1.程序分析：我们想办法把最小的数放到x上，先将x与y进行比较，如果x>y则将x与y的值进行交换，然后再用x与z进行比较，如果x>z则将x与z的值进行交换，这样能使x最小。-Enter the three integers x, y, z, please these three the number of small to large output. 1. Program analysis: We think of a way to put x number of the smallest, the first comparison of x and y, if x> y will be the value of x and y exchange and then to compare x and z, if x > z will be x and z values of the exchange, which will enable x minimum.

TLC2543是TI公司的12位串行模数转换器，使用开关电容逐次逼近技术完成A/D转换过程。由于是串行输入结构，能够节省51系列单片机I/O资源；且价格适中，分辨率较高，因此在仪器仪表中有较为广泛的应用。-TLC2543 is TI s 12-bit serial ADC, the use of switched-capacitor successive approximation technique to complete A/D conversion process. Because it is serial input structure, and can save 51 Series single-chip I/O resources and affordable, higher resolution, so the instrumentation are more widely used.

This the snake game... It s better to set the "step delay" to "0" before running, it requires fast processing. You can control the snake using arrow keys on your keyboard. All other keys will stop the snake. Press ESC to exit. -This is the snake game... It s better to set the "step delay" to "0" before running, it requires fast processing.
