This paper shows the development of a 1024-point radix-4 FFT VHDL core for applications in hardware signal processing, targeting low-cost FPGA technologies. The developed core is targeted into a Xilinx庐 Spartan鈩?3 XC3S200 FPGA with the inclusion of a VGA display interface and an external 16-bit da ...

Fast Fourier Transform power point The rectangular window introduces broadening of any frequency components [`smearing鈥? and sidelobesthat may overlap with other frequency components [`leakage鈥?. 鈥he effect improves as Nincreases 鈥owever, the rectangle window has poor properties and better c ...

Although some FX1-based devices may use the FX1鈥檚 CPU to process USB data directly (Port I/O Mode), most applica- tions use the FX1 simply as a conduit between the USB and external data-processing logic (e.g., an ASIC or DSP, or the IDE controller on a hard disk drive).

This is an matrix class which has been adapted for complex number computations. It ll be of help for digital signal processing simulations.

The purpose of this project is to make it possible to remotely switch on a Webasto Thermo Top C water heater that is used to pre-heat the heating system of a car without starting the motor.

The GIFT (the GNU Image-Finding Tool) is a Content Based Image Retrieval System (CBIRS: http://en.wikipedia.org/wiki/CBIR). It enables you to do Query By Example (QBE: http://en.wikipedia.org/wiki/QBE) on images, giving you the opportunity to improve query results by relevance feedback. For processi ...

The philosophy of the book is to present various pattern recognition tasks in a unified way, including image analysis, speech processing, and communication applications. Despite their differences, these areas do share common features and their study can only benefit from a unified approach.

Open-source, free, multi-platform BASIC compiler, with syntax similar MS-QuickBASIC (including the GFX statements), that adds new features such as pointers, unsigned data types, inline assembly, a pre-processor and many others.
