An Experimental and Analytical Study on the Improvement of False Path-switching in Auxiliary Radio Communication System Repeaters Using Digital Multichannel Filtering
Korean fire-safety standards such as the National Fire Performance Code (NFPC) 505 and the National Fire Technical Code (NFTC) 505 require that auxiliary radio communication systems do not impede digital radios. However, most repeaters and line amplifiers are analog path-switching devices driven by carrier detection, w...
