A filter is a device that passes or rejects certain frequencies of a signal. Three common type of filters are the low- pass filter the bandpass filter, and the high-pass filter. An ideal low-pass ...

The switched-capacitor (SC) techniques enable the design of various filters that can be realized in monolithic integrated circuits from using state-of-art MOS technology. By replacing the noisy ...

of ±200 Hz can be expected. Complicate the situation with a spur at 11.0 kHz. To reject the 11.0-kHz spur, you need a filter with very sharp rolloff, but to accommodate the wandering 10.0-kHz signal, ...

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 ...
