Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
146 words
A SYSTEM FOR TRANSLATING PHASE INFORMATION INTO AN AMPLITUDE-MODULATED CARRIER WAVE SIGNAL COMPRISING FIRST RESISTIVE MEANS FOR DERIVING FROM A GIVEN PHASE VECTOR COMPONENTS PROPORTIONAL TO THE SINE AND COSINE OF THE VECTOR ANGLE, A CARRIER WAVE SOURCE PRODUCING TWO ORTHOGONAL COMPONENTS OF THE SAME FREQUENCY, MEANS FOR AMPLITUDE MODULATING THE RESPECTIVE ORTHOGONAL COMPONENTS IN THE OUTPUT OF SAID WAVE SOURCE WITH THE SINE AND COSINE COMPONENTS FROM SAID DERIVING MEANS, MEANS FOR COMBINING THE MODULATED ORTHOLOGONAL COMPONENTS INTO A SINGLE OUTPUT WAVE AT SAID CARRIER FREQUENCY FOR TRANSMISSION TO A REMOTE POINT, MEANS AT SAID REMOTE POINT FOR SEPARATING SAID SINE AND COSINE COMPONENTS FROM SAID OUTPUT WAVE, FURTHER RESISTIVE MEANS FOR COMBINING SAID SEPARATED COMPONENTS INTO RESULTANT SIGNALS REPRESENTATIVE OF POSSIBLE TRANSMITTED PHASE VECTORS, AND MEANS FOR SELECTING THE SIGNAL FROM SAID FURTHER RESISTIVE MEANS OF MAXIMUM AMPLITUDE AS THE MOST PROBABLE TRANSMITTED PHASE.
