An apodized discrete layer thickness design method for notch filters is presented. The method produces error tolerant designs with low ripple in the pass band regions ...

This integrated CMOS switched-capacitor filter has all of its capacitors on-chip and requires only an external clock and a balanced 5V power-supply. Internally, it uses two operational ...

Active notch filters have been used in the past for applications like elimination of 50- and 60-Hz hum components. They have proven to be somewhat problematic from the standpoints of center frequency ...
