Digital filters provide an important role in the world of communication. This paper proposes a literature review related to design the digital filters for audio application using multi rate signal processing. One of the important applications in multi rate signal processing is sub band coding. Humming sounds are present in the speech signal which cannot be removed easily and without filtering c...

The designphilosophyfor thi~ set hasbeento minimizeRF signal processing in favor. of digital signal processing and to minimize hardware digital signal processing in favor of software digital signal processing. This philosophy has resulted in a unique architecture. This architecture is described ...

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...

bci is one of the most intriguing technologies among other hci systems, mostly because of its capability of recording brain activities. spelling bcis, which help paralyzed people to maintain communication, are one of the striking topics in the field of bci. in this scientific a spelling bci system with high transfer rate and accuracy that uses ssvep signals is proposed. in addition, we suggeste...

Electronic systems deal with signals that have a frequency spectrum with a wide range of frequency components. These frequency components require filter functions that may include isolation, rejection or attenuation depending on system implementation. Digital filters are systems that modify certain frequencies relative to others either by a digital computational process or by implementation of ...
