Description: 声卡数字频率计 PC中的声卡不仅能输出和录制各种音频信号，利用其内部的A/D（模拟/数字）转换器，通过编写程序还可以用来对外部的周期性的模拟信号进行采样，并计算出该信号的频率值。文中所述的作者设计的程序就是这样的一种程序，能够满足一般电子爱好者把PC作为数字频率计使用的要求。该程序是标准的Windows界面，界面友好，以黑色背景红色大号字体显示频率值，具有醒目、程序简洁和测量精度高的特点，-sound card number or frequency of PC sound card can not only output and recording audio signals, use its internal A/D (analog/digital) converter, through the preparation process could also be used to the cyclical external analog signal is sampled, and the calculated value of the frequency signal. Wen described the author of the design process is one of the procedures, to meet the general electronic enthusiasts use the PC as a digital frequency meter use requirements. The procedure is the standard Windows interface, the interface is friendly to the black background of red font tuba frequency, with catchy and simple procedures and high measurement accuracy characteristics,

Description: 笔记本高频噪音消除软件
适用情况：
打开一个音频文件，并使之暂停。如果此时您的笔记本噪音消失，则这个软件是适用的。
使用方法：
install用于安装消噪音软件。双击执行即可。
uninstall用于缷载消噪音软件。双击执行即可。windows\system32下有个denoise.dll，请在重启机器后手工删除（不删除也没有妨害）。
源程序在ca18.c。-High-frequency noise cancellation software notebook application: to open an audio file, and the suspension. If your notebook at this time the noise disappears, then this software is applicable. Usage: install the software for the installation of noise elimination. Implementation can double-click. uninstall for noise elimination缷containing software. Implementation can double-click. There is a windowssystem32 under denoise.dll, please restart the machine after the hand-delete (do not delete there is no prejudice). Source in ca18.c.

A PLD Based Delta-Sigma DAC
Delta-Sigma modulation is the simple, yet powerful,
technique responsible for the extraordinary
performance and low cost of today s audio CD
players. The simplest Delta-Sigma DAC consists of a
Delta-Sigma modulator and a one bit DAC. Since,
both of these components can be realized using
digital circuits, it is possible to implement a low
precision Delta-Sigma DAC using a PLD.-Using FPGA to achieve the DA converter, has descriptions and source code, VDHL document.

Description: 本人非常支持单片机设计DIY 在这里再次献出小弟的一点心意,下面是使用AT89S52驱动74HC4015,实现1选择8的数据通道切换器,可以在不8个通道出加上不同大小的电阻.可以用来单声道音量的大小控制.
下面作品图是小弟设计的廉价的 基于单片机的毕业设计 ,它还使用了无线接收发送模块,通过使用手上的遥控器能控制音量的大小,还加了一块HCF4052用于输入音道的选择,支持思路音频信号的输入,一路音频信号的输出:
-I very much support the single-chip design DIY here again gave a little boy s mind is to use the following AT89S52 drive 74HC4015, to achieve a choice of 8 switches the data channel, you can not add the 8-channel resistance of different sizes. Can used to the size of mono volume control. The following work plan is designed小弟cheap graduation based on single-chip design, it uses the wireless receiver send module, through the use of the hands of the remote control can control the volume size, but also Add a piece of HCF4052 Road for the importation of sound choices, to support the idea of audio signal input, the output audio signal all the way:
