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:

本系统利用凌阳SPCE061A单片机原理,设计了一种双向超声测距系统,与一般的超声测距系统相比,除具备一般测距系统具有的功能外,该系统还具有低功耗、高精度、工作可靠、人机交互界面友好等优点。由于超声传播速度与环境温度相关而采用声速温度自动补偿技术,根据测量不同距离和不同的反射材料,回波信号强度从几毫伏到几百毫伏变动,因而采用两片AD603组成AGC自动增益控制电路与低噪放大器 NE5532 级联使用的方式组成超声检测信号放大电路,提高超声检测系统的检测范围和系统的适应性,使的系统获的较好的整机性能。由于超声波的传播距离与它的振幅成正比,为了使测距范围足够远,可对单片机输出方波信号进行功率放大后再加在超声波换能器上,因而先由三极管8050进行功率放大,再通过由六非门CD4049接成推挽方式的驱动电路将振荡信号的幅度放大一倍,再接到超声波换能器,从而增加了超声波的传播距离,扩大了测距范围。-err

Studied this subject can be stored as a virtual oscilloscope
本课题所研究的可存储虚拟示波器定位为低档型,即在性能上只需满足大多场合的基本应用,努力实现小型化,价格尽可能低廉,这样在财力有限的小用户(电子爱好者、小型企业)中能够普及,在大用户的使用中发挥便携性强的优势,与高档示波器配合使用,互相取长补短。-Studied this subject can be stored as a virtual oscilloscope-type low-grade, that is, in terms of performance on most occasions, only to meet the basic application, and strive to realize miniaturization and low prices as much as possible so that limited financial resources to small users (electronic enthusiasts, small enterprises) can be universal, in the use of large users to play a strong advantage of portability, high-end oscilloscope used in conjunction with each other.
