Until recently, audio systems have largely been analog. Now the trend is moving rapidly to digital implementations. While the literature contains most of the information needed to design and implement ...

This article is part of the Ideas for Design Series: Vol. 3, No. 9. Many communications and sensor applications require a bandpass filter with wide bandwidth. This filter typically requires precision ...

Current‐mode all‐pass filters represent a crucial class of signal processing circuits that, by utilising current signals rather than voltage signals, offer inherent advantages in terms of integration, ...
