Powerline Notch Filter
Introduction for the Powe Line Adptave Filter
EDR’s PLAF (power line adaptive filter) was designed around the EDR 82534 multi-notch (comb) reject filter. The PLAF is a stand-alone unit created for use in the detection of natural electromagnetic waves at remote locations and seismic data collection, biomedical and other scientific and industrial applications. EDR’s notch filter is a very unique device. It substantially reduces electrical noise caused by power sources without altering the waveforms of an input signal.
