模拟正弦衍射光栅光强分布，图1中X轴是位置，Y轴是光强，图2，是强度分布(Analog sinusoidal diffraction grating intensity distribution)

The program computes and plots the equation of time, the declination, and an analemma curve for various orbital parameters. The analemma is the curve traced by the position of the sun, measured at clock noon, over a year.

SINE PWM FINAL SIMULATION

IIR滤波器设计 一、 实验目的 1、 掌握冲激响应法和双线性变换法设计IIR滤波器的原理及具体设计方法，熟悉用双线性设计法设计低通、带通和高通IIR数字滤波器的计算机程序； 2、 熟悉模拟Butterworth滤波器和Chebyshev滤波器的设计，掌握冲激响应法和双线性变换法设计数字IIR滤波器的方法。 (IR filter design, the purpose of the experiment master IIR filter impulse response method and the bilinear transform design principles and specific design method, familiar with the the bilinear design method to design low pass, band-pass and high-pass IIR digital filter is a computer program familiar analog Butterworth filter and Chebyshev filter design, master the impulse response method and the bilinear transform design digital IIR filter method.)

把批量的可控源大地电磁测深数据转换为EH4格式数据，以适用于winglink反演。(Convert the CSAMT sounding bulk data to EH4 format data, in order to apply the winglink inversion.)
