Description: 针对DVB-T标准ETSI EN 300 744 V1.5.1,设计了可用于DVB-T接收整机的多速率DDC模块,并在FPGA中仿真实现.在复用数字振荡混频模块的基础上,根据输入信号的不同带宽(6M/8MHz)选择不同的抽取滤波器组完成抽取因子为3或4的多速率处理任务,利用两级半带滤波器(HBF)级联完成4倍抽取滤波,单级奈奎斯特滤波器完成3倍抽取滤波.-For the DVB-T standard ETSI EN 300 744 V1.5.1, designed for DVB-T receiver machine multi-rate DDC module, and the simulation in the FPGA implementation. Numerical oscillation in the complex mixer module, based on the input signals of different bandwidths (6M/8MHz) choose a different group of complete decimation filter extracted factor 3 or 4 of the multi-rate processing tasks, using two half-band filter (HBF) cascade to complete four times decimation filter, single-stage Chennai Nyquist filter to complete three times the decimation filtering.

Description: Audio Mixer函数缩进一组控制音频线到目标设备的函数，并也可以控制音量和其他效果。在这组API中，尽管只有十个函数和两个消息，但使用起来还是比较难。本在本节中，通过应用这些函数编写成3个应用程序，来展示它们的使用方法。而且，尽可能采用实际应用中的用户界面，这样，更有可能被读者直接利用。
-Audio Mixer Functions indent a line to the target device controls the audio functions, and also can control the volume and other effects. In this group of API, although only 10 functions and two messages, but it is still more difficult to use. This In this section, through the application of the preparation of these functions into three applications to demonstrate their use. Moreover, as far as possible the practical application of the user interface, so that readers are more likely to be the direct use of.

Description: 在本系统中，信息序列在先经过FSK调制，经过截止频率为25kHz的低通滤波器后（把信号频率限制在25kHz），再进入混频器搬移到更高的频率发送出去，在接收端，用与发送端同步的跳频信号对其进行变频（跳频的解跳处理在此进行），取下边频，然后进行FSK的解调-In this system, the message sequence prior through FSK modulation, through the cut-off frequency of 25kHz after low-pass filter (to limit the frequency 25kHz), and then move into the mixer to a higher frequency to send out, at the receiving end used with frequency hopping synchronization signal transmitter carried on their conversion (FH' s solution to deal with this for jumping), take down side frequencies, then the demodulation of FSK

Description: 文件包中有三个文件：sound.c,mixer.c.vol.c
其中sound.c是实现打开、关闭音频接口，同时实现录音放音功能的文件；
mixer.c是实现读取当前混音器的设备信息，设置左、右声道增益功能的文件；
vol.c是实现调节音量功能的文件
此文件是基于linux开发板编写的-Package has three files: sound.c, mixer.c.vol.c sound.c which is to achieve open, close the audio interface, simultaneous recording playback function in the file mixer.c read the current mixer to achieve the device information, setting the left and right channel gain function file vol.c adjust the volume function is to achieve a document This document is prepared based on linux development board
