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 ...

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 ...

How an electro-optic PIC can implement RF filtering functions. Which E-O components are needed for passband and notch filtering. How the overall device was fabricated and the test results. It’s a very ...

The usual schematic of a state-variable filter with two inverting integrators is well known. Curiously, the input signal is almost always connected to the minus input of U1. Figure 1 is an example ...
