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
