Notch filters are commonly called suppression filters, band-stop filters, etc. The characteristic of this filter is that it can pass most wavelengths with almost no loss, and the specified band (stop ...

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 ...

Two new notch filters with built-in ESD protection functionality have employed proprietary materials and advanced structural design to implement attenuation characteristics for specific frequency ...

An array of electro-optical components fabricated as a silicon-based photonic IC provides narrowband passband and notch filtering above 10 GHz. How an electro-optic PIC can implement RF filtering ...
