José Silva-Martínez,Michiel Steyaert,Willy Sansenversity, estuarine tubificids tend to become more important, while in tidal freshwater areas these conditions result in little change in community composition. The common bond between the faunas inhabiting tidal freshwater and estuarine areas is their opportunistic nature.

Introduction,, active filters ranging from a few kiloHertz (kHz) up to several MegaHertz (MHz) are required. Some other communication systems like radio and video frequency receivers demand high-frequency and high-selectivity analog filters as well.

High-Performance Realizations of Continuous-Time Filters,d in chapter 2. The quality factor (e.g. the passband ripple) of the filters is controlled by full CMOS resistors. These resistors have been discussed in chapter 3. The automatic tuning systems described in chapter 4 are used for the control of a 10.7 MHz bandpass filter.
