Active band reject filters are tuned circuits that prevent the passage of signals within a specified band of frequencies.

Signal filters block or decrease (attenuate) unwanted frequencies or signal wave characteristics.

RF filters and microwave filters are devices that pass or reject signals by frequency.

RF band reject filters are tuned circuits that prevent the passage of signals within a specified band of frequencies.

Charge converters and charge amplifiers convert the charge output from a piezoelectric, capacitive or other charge-producing sensor to a signal such as analog voltage or current.

Instrumentation amplifiers are differential amplifiers that have been optimized for use with DC signals.

Data acquisition systems and instruments collect, digitize and process multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes.
