  • ASR M08-B资料

    ASR M08-B设置软件 V3.2  arduino 2560+ASRM08-B测试程序  arduino UNO+ASRM08-B测试程序语音控制台灯电路图及C51源码(不带校验码) 继电器模块设置。   ASR M08-B是一款语音识别模块。首先对模块添加一些关键字,对着该模块说出关键字,串口会返回三位的数,如果是返回特定的三位数字,还会引起ASR M08-B的相关引脚电平的变化。【测试】①打开“ASR M08-B设置软件 V3.2.exe”。②选择“串口号”、“打开串口”、点选“十六进制显示”。③将USB转串口模块连接到语音识别模块上。接线方法如下:语音模块TXD --> USB模块RXD语音模块RXD --> USB模块TXD语音模块GND --> USB模块GND语音模块3V3 --> USB模块3V3(此端为3.3V电源供电端。)④将模块的开关拨到“A”端,最好再按一次上面的大按钮(按一次即可,为了确保模块工作在正确的模式)。⑤对着模块说“开灯”、“关灯”模块会返回“0B”、“0A”,表示正常(注意:0B对应返回值010,0B对应返回值010,返回是16进制显示的嘛,设置的时候是10进制设置的)。

    zemax源码: This DLL models a standard ZEMAX surface type, either plane, sphere, or conic The surface also demonstrates a user-defined apodization filter The filter is defined as part of the real ray trace, case 5 The filter can be used at the stop to produce x-y Gaussian apodization similar to the Gaussian pupil apodization in ZEMAX but separate in x and y. The amplitude apodization is of the form EXP[-(Gx(x/R)^2 + Gy(y/R)^2)] The transmission is of the form EXP[-2(Gx(x/R)^2 + Gy(y/R)^2)] where x^2 + y^2 = r^2 R = semi-diameter The tranmitted intensity is maximum in the center. T is set to 0 if semi-diameter < 1e-10 to avoid division by zero.

  • PlotSphereIntensity(azimuth, elevation) PlotSphereIntensity(azimuth, elevation, intensity) h = Plo

    PlotSphereIntensity(azimuth, elevation) PlotSphereIntensity(azimuth, elevation, intensity) h = PlotSphereIntensity(...) Plots the intensity (as color) of a number of points on a unit sphere. Input: azimuth (phi), in degrees elevation (theta), in degrees intensity (optional, if not provided, a green sphere is produced) All inputs must be vectors or matrices of the same size. Data does not have to be evenly spaced. When there aren t enough points to draw a smooth sphere, additional points (with color) are interpolated. Output: h - a handle to the patch object The axes are also plotted: positive x axis is red positive y axis is green positive z axis is blue

    P3.20. Consider an analog signal xa (t) = sin (2πt), 0 ≤t≤ 1. It is sampled at Ts = 0.01, 0.05, and 0.1 sec intervals to obtain x(n). b) Reconstruct the analog signal ya (t) from the samples x(n) using the sinc interpolation (use ∆ t = 0.001) and determine the frequency in ya (t) from your plot. (Ignore the end effects.) C) Reconstruct the analog signal ya (t) from the samples x (n) using the cubic spline interpolation and determine the frequency in ya (t) from your plot. (Ignore the end effects.)
