sv fifo 环境

本程序是锁相环的仿真程序，具有接收端载波同步的功能。注释详尽，程序规范。发端的调制方式有单载波调制，BPSK调制，QPSK调制可供选择。程序中有星座图，锁相环的频差、相差图，以及解调后的基带波形。(This program is a phase-locked loop simulation program, the with carrier synchronization receiving end function. Notes detailed program specifications. The originator of the modulation scheme to choose a single carrier modulation, BPSK modulation, QPSK modulation. Program constellation diagram, the PLL frequency difference, a difference of FIG, and the demodulated baseband waveform.)

i2c配置SAA7113，非常有用的程序，做视频采集类必看(i2c configure SAA7113)

说明：  利用stm32F407实现的等精度测频，可以精确测量频率，误差很小(The equal precision frequency measurement realized by stm32F407 can accurately measure frequency with little error.)

说明：  对delta sigma进行设计，实现delta sigma ADC的设计(this is use for delta sigma adc ,and design and achieve adc)
