Real-time programmable audio bandwidth filter incorporating a high-level design interface

    Research output: Contribution to journalArticlepeer-review

    Abstract

    A simple but highly integrated digital signal processing system is described for real time filtering of audio bandwidth signals. It includes the necessary processing and communications hardware, the processing code itself, and a high-level software interface that enables the user to design and download arbitrary finite impulse response filters to the run-time system. The filter coefficients are calculated using the Frequency Sampling Method. A unique feature of the design is the manner in which the software and hardware components have been organized as an intelligent system, obviating on the part of the user a detailed knowledge of filter design theory or any abilities in processor architecture and assembly code programming.
