Active Notch Filter

Introduction for the 50/60Hz notch filter:


multi-notch (comb) reject filter The EDR 82534 is a low cost, multi-notch (comb) reject filter for low frequency signal applications.  A Power interference or band stop filter is an important and needed sub-component to design and build medical recording systems where minute bioelectric signals, on the order of mill volts to microvolts are measured.  In the operation room, the cath lab, or in research facilities there is always a substantial level of electrical interference produced by local power lines.  EDR’s filter is not just a notch filter; it is a significant advancement in analog/digital filtering technology.
