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 ...

This amplifier-based IC implements dual low-pass filters with matched response at cutoff frequencies up to 10 MHz. To build active filters for high-frequency RF applications, designers may construct ...
