Quick Take: “Bits, Bytes and Chips” by Armstrong & Csermak looks at hearing aid digital signal processing (DSP) as the first DSP hearing aids were coming available in 1999. The authors explain sampling rates, MIPs, and detail how the A/D converter (analog-to-digital) can limit the performance of hearing aids. They also discuss the concepts of the noise floor, dynamic range, sampling resolution, over-sampling, and noise shaping as they pertain to hearing aid performance.
Author biographies in January 1999: Brian Csermak is applications engineer and Steve Armstrong is senior marketing manager at Gennum Corp, Burlington, Ontario, Canada.
