本文设计了基于加速度传感器的计步器，并通过仿真以及实际调试得到了相应的结果的记录。本实验首先通过加速度传感器检测目标物体的运动，产生脉冲，将脉冲放大后经过施密特触发器整型为方波，并给出了方波的调试电路图。然后编写程序，利用D触发器检测方波的上升沿，当上升沿到来时，计数，并对十位、个位分别编码，然后由使能信号交替控制数码管输出结果。本文给出了仿真以及调试的程序、结果。(This article is designed pedometer-based acceleration sensor and the corresponding results recorded by simulation and debugging. The experiments by first acceleration sensor detects the movement of the target object, generates a pulse, the pulse amplification is a square wave after the Schmitt trigger integer, and gives the the debug circuit diagram of a square wave. Then write procedures, the use of the rising edge of the detection of the square wave of the D flip-flop, when the rising edge, the count, and ten bits are encoded, and then alternately by the enable signal output of the digital control. In this paper, a simulation and debugging procedures, results.)

蒙特卡洛仿真图 这个程序对2psk信号进行仿真 前提是把信号能量归一化了 (This programme intend to realize the simulation of 2DPSK through MonteCarlo experiment. intends )

BT656转RGB的算法实现代码，使用VORILOG语言编写(BT656-->RGB, verilog)

可以产生ASK FSK PSK 等调制信号。非常好用已经实现了所有功能。在硬件测试通过了(Can generate ASK FSK PSK modulated signals and so on. Is very easy to use all the features has been achieved. On the hardware test of the)

1、 利用FLEX10的片内RAM资源，根据DDS原理，设计产生正弦信号的各功能模块和顶层原理图； 2、 利用实验板上的TLC7259转换器，将1中得到的正弦信号，通过D/A转换，通过ME5534滤波后在示波器上观察； 3、 输出波形要求： 在输入时钟频率为16KHz时，输出正弦波分辨率达到1Hz； 在输入时钟频率为4MHz时，输出正弦波分辨率达到256Hz； 4、 通过RS232C通信，实现FPGA和PC机之间串行通信，从而实现用PC机改变频率控制字，实现对输出正弦波频率的控制。-a use FLEX10-chip RAM resources, in accordance with DDS principle, design sinusoidal signal generated by the top-level functional modules and schematics; 2, the experimental board TLC7259 converters, will be a sinusoidal signal, the D/A conversion, after filtering through the ME5534 oscilloscope observation; 3, the output waveform requirements : the input clock frequency of 16KHz, sine wave output resolution of 1Hz; the input clock frequency of 4MHz, the sine wave output resolution of 256Hz; 4, RS232C communications, FPGA and PC serial communications between in order to achieve PC-frequency control characters, the realization of sine wave output frequency control.
