Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...

Analog filter design remains a cornerstone of modern signal processing, instrumental in a vast array of applications spanning telecommunications, instrumentation, and biomedical engineering. Recent ...

Analog signal processing has conventionally been viewed as a voltage-dominated form of design. But voltage-mode processing can restrict the system's dynamic range. There is also a limitation on the ...

The D68 series of analog filters from Frequency Devices have Total Harmonic Distortion levels as low as -100 dB with near theoretical frequency responses and low noise. The D68 filters are available ...

Analog filters implemented in CMOS technology continue to be a cornerstone in the development of modern electronic systems. By integrating active components such as operational transconductance ...

Editor’s note: I came across this excellent tutorial article on Digital Filter Design and I thought it would be an excellent guide for novices as well as seasoned veterans. I want to thank William H.
