INTRODUCTION In the past, adding speech recording and playback capability to a product meant using a digital signal processor or a specialized audio chip. Now, using a simplified Adaptive Differential Pulse Code Modulation(ADPCM) algorithm, these audio capabilities can be added to any PICmicro device. This application note will cover the ADPCM compression and decompression algorithms, performance comparison of all PICmicro devices, and an application using a PIC16C72 micro-controller.DEFINITION OF TERMS step size -value of the step used for quantization of ana-log signals and inverse quantization of a number of steps.quantization -the digital form of an analog input signal is represented by a finite number of steps.adaptive quantization -the step size of a quantizer is dramatically changed with time in order to adapt to a changing input signal.inverse quantizer -a finite number of steps is converted into a digital representation of an analog signal.

German universities and scientists have repeatedly set the intermational standard in drive technology. Identification and active compensation of natural frequencies in oscillatory mechanics, status controls with monitoring structures incorporating acceleration sensors, adaptive compensation of measurement system deficiencies, self-adjusting detent torque compensation… everything invented with only a single aim in mind: to continue improv-ing the motion control, dynamics, precision and processing speed of your machines. For the industrial applicabability of this technology scientific publications in proceedings and laboratory test rigs are not enough. These features consequenty need to be converted into cost-efficient and easily manageable products. That 's exactly what we have done.So in future, if you should need more than today ' smarket can offer you, now everything isgoing to be alright. With our new high-performance ServoOne drive series you will experi-ence

Note: Before commissioning the value of the connected mains voltage must be set in the servo controller(factory setting=3×400 V AC). More detailed information see chapter 4"Commissioning".通讯接口所有的Servo-One系列均有USB及TCP/IP通讯接口，可通过LT-I公司的Drive-Manager5软件进行通讯，进行相关参数的读写和现场调试，详情请参考章节.…软件调试。Servo-One Junior:X9（USB1.1）TCP/IP（开发中）Servo-One:X2（USB1.1）X3（TCP/IP）Note: The faults can be acknowledged in accordance with their programmed reaction(ER) or reset via a 24 V-reset(X9/10)(ER.).Attention: Faults marked with a dot can only be reset, after the cause of the fault has been eliminated.显示为当前版本V5.4.0同时，相应的USB接口驱动也在对应的安装文件夹内，例：C:\Program FileLTI DRiVES GmbHILTi DriveManager 5.4.0drivers

Introduction The Sil9135/Sil9135A HDMI Receiver with Enhanced Audio and Deep Color Outputs is a second-generation dual-input High Definition Multimedia Interface(HDMI)receiver. It is software-compatible with the Sil9133receiver, but adds audio support for DTS-HD and Dolby TrueHD. Digital televisions that can display 10-or 12-bit color depth can now provide the highest quality protected digital audio and video over a single cable. The Sil9135and Sil9135A devices, which are functionally identical, can receive Deep Color video up to 12-bit,1080p @60Hz. Backward compatibility with the DVI 1.0specification allows HDMI systems to connect to existing DVI 1.0 hosts, such as HD set-top boxes and PCs. Silicon Image HDMI receivers use the latest generation Transition Minimized Differential Signaling(TMDS) core technology that runs at 25-225 MHz.The chip comes pre-programmed with High-bandwidth?

程序结构在Arduino中，标准的程序入口main函数在内部被定义，用户只需要关心以下两个函数：setup）当Arduino板起动时setup（）函数会被调用。用它来初始化变量，引脚模式，开始使用某个库，等等。该函数在Arduino板的每次上电和复位时只运行一次。1oop0在创建setup函数，该函数初始化和设置初始值，1oop（O函数所做事的正如其名，连续循环，允许你的程序改变状态和响应事件。可以用它来实时控制arduino板。示例：控制语句if if，用于与比较运算符结合使用，测试是否已达到某些条件，例如一个输入数据在某个范围之外。使用格式如下：该程序测试value是否大于50。如果是，程序将执行特定的动作。换句话说，如果圆括号中的语句为真，大括号中的语句就会执行。如果不是，程序将跳过这段代码。大括号可以被省略，如果这么做，下一行（以分号结尾）将成为唯一的条件语句。
