Patent Number Title Of Patent Date Issued
5249232 Data processing system having an encryption device September 28, 1993
A data-processing system includes an address bus and a data bus operatively coupled to a central processing unit, main memories, and control circuits for peripheral equipment, information carried on the data bus being encrypted. An encryption and decryption device is operatively coupled
4955039 Quadrature receiver September 4, 1990
A quadrature receiver is disclosed which contains two mixers (M1, M3) in an in-phase receiving path and two mixers (M2, M4) in a quadrature receiving path for converting a received signal to a low IF. Each of the mixers is fed with an oscillator signal (O1 through O4), with the oscillato
4757535 System for encrypted information transmission July 12, 1988
A system for encrypted information transmission is disclosed in which so-called recording interference is suppressed. Encryption is effected by means of a periodically recurring pseudo-noise sequence (key word). Synchronization between transmitter and receiver is produced by means of a
4718113 Zero-IF receiver wih feedback loop for suppressing interfering signals January 5, 1988
A working on the zero IF principle is disclosed which contains a feedback circuit instead of a preselector for suppressing interfering signals. The interfering signals contained in the incoming signal (F.sub.E) are separated from the useful signal by filters in the baseband. They are the
