Modern computer technology has opened up new opportunities for the development of digital signal processing methods [...]

A lthough real world signals are analog, it is often desirable to convert them into the digital domain .using an analog to digital converter (ADC). Motivating designers to apply this conversion is the efficient transmission and storage of digital signals. Digital representation of an audio signal, for example, allows CD players to achieve virtually error free storage using optical disks [l]. In...

The development of FPGA-based digital signal processing devices has been gaining attention. Researchers seek to reduce power consumption and enhance signal processing quality in these devices with given resources and spatial limits. Hence, there is a need to investigate both the capability and the power consumption associated with the various digital filtering schemes commonly used in FPGA-base...

Digital filters are widely used in many digital signal processing applications. Therefore, digital filtering is one of the basic needs of digital signal processing. This paper introduces the definition and basic principles of FIR digital filters, and the design based on MATLAB.After the description of the process of design, the matlab program is used to implement FIR filter using modified coeff...

Digital watermarking is a very recent research area. Digital audio watermarking is a method to embed or hide the Watermark (Information signal) into a digital signal i.e. Image, audio, text or video data. The watermark is difficult to remove from the audio signal. If the signal is copied, the information or watermark is also carried in the copy. A signal may carry several different watermarks a...
