  • A real-time and simultaneous processing system with 8 analog inputs is designed. The system is based on the development of Texas Instrument TMS320VC5510 DSK kit. The analog input signals are converted into digital ones by 8 bit ADC module using ADC0809. The ADC module interfaces to the DSP in parallel, through the DSP’s Memory Expansion Connector. The measurement with standard input signals fom FUNCTION GENERATOR LG1311 is also reported.

  • Java offers several benefits that could facilitate the use of wireless Personal Digital Assistants (WPDAs) for the user. First, Java is portable, and that means that it is independent of the hardware platform it runs on, which is very important for reducing the cost of application development. As Java can be run anywhere, the development of applications can be done on a desktop without the need of a real hardware platform.

  • The increasing demand for communications services and the desire for increased data throughput in modern communications systems has fueled research and development into the use of adaptive antenna arrays. Since frequency bandwidth is in short supply and is expensive to acquire, the ability to separate users based on their spatial parameters is very attractive for wireless networks. Adaptive antenna arrays offer the ability to increase the Signal-to-Noise Ratio (SNR) of a wireless communication link while at the same time permit the cancellation and removal of co-channel interference. ...

  • The Fast Fourier Transform It is difficult to overstate the importance of the FFT algorithm for DSP. We have often seen the essential duality of signals in our studies so far; we know that exploiting both the time and the frequency aspects is critical for signal processing. We may safely say that were there not a fast algorithm for going back and forth between time and frequency domains, the field of DSP as we know it would never have developed. The discovery of the first FFT algorithm predated the availability of hardware capable of actually exploiting it. ...

Echo is usefully employed in sonar and radar for detection and exploration purposes. In telecommunication, echo can degrade the quality of service, and echo cancellation is an important part of communication systems.

  • The Verilog hardware description language (HDL) provides the ability to describe digital and analog systems. This ability spans the range from descriptions that express conceptual and architectural design to detailed descriptions of implementations in gates and transistors. Verilog was developed originally at Gateway Design Automation Corporation during the mid-eighties. Tools to verify designs expressed in Verilog were implemented at the same time and marketed. Now Verilog is an open standard of IEEE with the number 1364.

  • Experts in every field of study depend on specialized tools. In the case of speech research and development, the dominant tools today are computer programs. In this article, we present an overview of key technical approaches and features that are prevalent today. We restrict the discussion to software intended to support R&D, as opposed to software for commercial applications of speech processing. For example, we ignore DSP programming (which is discussed in the previous article). Also, we concentrate on software intended to support the special-...
