基于单片机的数字化B超键盘设计

针对目前使用的RS232接口数字化B超键盘存在PC主机启动时不能设置BIOS，提出一种PS2键盘的设计方法。基于W78E052D单片机，采用8通道串行A/D转换器设计了8个TGC电位器信息采集电路，电位器位置信息以键盘扫描码序列形式发送，正交编码器信号通过XC9536XL转换为单片机可接收的中断信号，软件接收到中断信息后等效处理成按键。 ...

基于AR模型的HIFU无损测温方法研究

自回归功率谱密度（AR-PSD）方法的基础是生物组织的离散散射体模型〔超声体模〕理论，该模型认为生物组织为半规则的散射体分布的，这种方法是基于温度和频移的相关特性。本文介绍超声回波信号对HIFU（High Intensity Focused Ultrasound）治疗的测温技术，从测温模型和算法，实验仪器的设计和构建，仿真和离体实验中获取了 ...

The frequency domain plays an important role in image processing to smooth, enhance, and detect edg

The frequency domain plays an important role in image processing to smooth, enhance, and detect edges of images. Although image data typically does not include imaginary values, the fast Fourier transform (FFT) has been used for obtaining spectra. In this paper, the fast Hartley transform (FHT) is u ...
