Title: Digital filtering of band-pass signals with phase-quadrature mixing
Inventor: SERBE CHRISTOPH PETER
IPC: H03H17/06
Filed: 1994-12-13
Granted: 1995-08-24
Abstract: The in-phase and quadrature channels are mixed (IQM1) with a quarter of the sampling rate of the input signal. A single interpolator (IP1) calculates the sample values of the Q channel. The samples from both channels are balanced prior to half-band filtering (HBF1) and decimation (DZ1).  An I-Q re-mixer (IQR1) then combines the two partial signals into a single output, at a sampling rate which is only half of the decimated sampling rate in the separate channels.

Patent DE-4446211-C1 (DE)
Inventor: GRABOWSKI ALEXANDER DIPL CHEM
IPC: C02F1/44
Filed: 1994-12-23
Granted: 1995-10-26
Abstract: In order to treat water contaminated with warfare agents and containing less than 500 ppm of salt, a separation stage (10) is normally provided downstream of the reverse osmosis. In the separation stage, the untreated water is divided into residue and permeate. Warfare agents have the property of acting as softeners on the semi-permeable organic polymer membranes of separation stages. As a result of this, the warfare agents pass through the membranes of separation stages in increasing quantities once the latter have been in operation for a few hours. In order to improve the treatment of water contaminated with warfare agents, salt is added to the untreated water which, with a salt content of over 1000 ppm, is then drawn through the separation stage (10) downstream of the reverse osmosis stage. The invention is suitable for use with mobile facilities used for producing drinking water.
