When almost any electronic system passes a certain level of complexity, it requires some sort of filtering—often several types. However, many designers with a predominantly digital background may ...

The two T-notch filter can be used to block unwanted frequencies or if placed in an op amp as a bandpass filter. the notch frequency occurs where the capacitive reactance equals the resistance (Xc = R ...

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 ...

This article is part of the Ideas for Design Series: Vol. 3, No. 9. Many communications and sensor applications require a bandpass filter with wide bandwidth. This filter typically requires precision ...
