The 4.0 kbit/s speech codec described in this paper is based on a Frequency Domain Interpolative (FDI) coding technique, which belongs to the class of prototype waveform Interpolation (PWI) coding techniques. The codec also has an integrated voice activity detector (VAD) and a noise reduction capabi ...

在包 hugeinteger 中创建功能类 HugeInteger，该类用来存放和操作一个不超过 40 位的大整数。 (1) 定义一个构造函数，用来对大整数进行初始化。参数为一个字符串。 (2) 定义 input 成员函数，实现大整数的重新赋值。参数为一个字符串，无返回 值。 (3) 定义 output 成员函数，将大整数输出到屏幕上。无参数无返回值。 (4) ...

transimpedance linearization circuitry. This allows it to drive video loads with excellent differential gain and phase perfor mance on only 50 mW of power. The AD8001 is a current feedback amplifier and features gain flatness of 0.1 dB to 100 MHz while offering differential gain and ph ...

Two important microwave remote sensors are the radar and the radiometer. There have been a number of books written on various aspects of radar, but there have been only a few written on microwave radiometers, especially on sub- jects of how to design and build radiometer systems. This book, which is ...

The Internet of Things is considered to be the next big opportunity, and challenge, for the Internet engineering community, users of technology, companies and society as a whole. It involves connecting embedded devices such as sensors, home appliances, weather stations and even toys to Internet Prot ...

This book is intended to help electric power and telephone company personnel and individuals interested in properly protecting critical tele­ communications circuits and equipment located in high voltage (HV) environments and to improve service reliability while maintaining safe working conditions. ...

This book is intended for the graduate or advanced undergraduate engineer. The primary motivation for developing the text was to present a complete tutorial of phase-locked loops with a consistent notation. I believe this is critical for the practicing engineer who uses the text as a self-study guid ...

In a cellular communication system, a service area or a geographical region is divided into a number of cells, and each cell is served by an infrastructure element called the base station through a radio interface. Management of radio interface related resources is a critical design component in cel ...
