Description: 该高频正弦信号发生器基于直接数字频率合成（DDS）和数字锁相环技术（DPLL），以微控制器（MCU）和现场可编程逻辑门阵列（FPGA）为核心，辅以必要的外围电路设计而成。系统主要由正弦信号发生、红外遥控、高速模数（A/D）－数模（D/A）转换、信号调制和后级处理等模块组成。-The high-frequency sinusoidal signal generator based on Direct Digital Synthesis (DDS) and digital PLL (DPLL), a microcontroller (MCU) and field programmable gate array (FPGA) as the core, supplemented by the necessary peripheral from circuit design. System is composed of sinusoidal signal, infrared remote control, high-speed module (A/D)- digital-analog (D/A) conversion, signal modulation and post-level processing modules.

Description: 读取高程数据的MATLAB程序,经过测试，很不错的，希望对大家有帮助- read_SRTMtile: returns lon, lat, & height (height in meters) SRTM 3-arcsec data
USE: [vlon vlat vhgt] read_SRTMtile(filename,sc)
INPUT:
filename: filename, e.g. s23w041.hgt
sc: spot check, any value here will produce a low resolution
image of tile (note: image rendering can be time consuming)
OUTPUT:
vlon: cell longitude
vlat: cell latitude
vhgt: cell height (in meters)
NOTES:
+ SRTM 3-arc sec data can be downloaded from:
http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/
(as per http://www2.jpl.nasa.gov/srtm/)
+ filename is parsed to obtain lower left (LL) coordinates of tile
(as per quickstart.pdf doc in:
http://dds.cr.usgs.gov/srtm/version2_1/Documentation/
File names refer to the latitude and longitude of the lower
