A filter that minimizes in-band noise and maximizes detection sensitivity of exponentially-modulated signals
Dynaspot Corp.
May 18, 2017 - N°20170141761

The trans-filter compresses in band awgn, demodulates input signals and has no threshold due to applied noise. Two frequency selective networks with opposite amplitude vs frequency slopes are designed to remain 180 degrees out of phase over the signal band. Output amplitudes are equal at band center and are summed producing a monotonic amplitude vs frequency characteristic going thru zero at ...
