Abstract

A fast operating phase-shift-controlled system for transmitting information in which a simulated sine wave is generated digitally and in which the phase of the generated wave is shifted solely at the 0* and 180* points to eliminate '"'"''"'"''"'"''"'"'ringing'"'"''"'"''"'"''"'"' and thereby increase the speed at which data may be transmitted.

Claims

1. The method of generating intelligence, said method comprising the steps of generating a first voltage wave comprising an integral number of first stepped half waves of voltage, each of said first half waves being of substantially sinusoidal form, each of said half waves comprising a first series of first spaced pulses of voltage, the amplitudes of each said first pulses having a selected relationship relative to the angle at which each said first pulse occurs in each of said first half waves, said selected amplitudes being directly proportional to the sine of the angle at which each such said first pulse occurs in its respective said first half wave, the total angle of each of said first half waves being substantially 180* , said total angle being the angle between the said angle at which said first pulse occurs and the said angle at which the next subsequent said first pulse occurs, of subsequently generating a second voltage wave comprising an integral number of second stepped half waves of voltage, each of said second half waves being of substantially sinusoidal form, each of said second half waves comprising a second series of second spaced pulses of voltage, the amplitudes of each said second pulses having a desired relationship relative to the angle at which each such said second pulse occurs in each of said second half waves, said desired amplitudes being directly proportional to the sine of the angle at which each such said second pulse occurs in its respective said second half wave, the total angle of each of said second half waves being substantially 180*, said total angle being the angle between the said angle at which said second pulse occurs and the said angle at which the next subsequent said second pulse occurs, of terminating the generation of said first voltage wave with the last said first pulse which completes the said total angle of the last to occur of said first half waves of said first voltage wave and of thereafter initiating the generation of said second stepped wave with a said second half wave having the same polarity as the last said first half wave of said first voltage wave.

2. The method of claim 1 in which said total angles of all of said half waves of said first waves are of equal magnitude and in which said second total angles of all of said half waves of said second wave are of equal magnitude.

3. The method of claim 2 in which said first and second magnitudes are equal to each other.

4. In an intelligence transmitting apparatus, first means providing a first stepped wave of voltage which is substantially sinusoidal and which includes at least one first half cycle, each said first half cycle pulsating in magnitude from an initial to a final value said means further providing a second stepped wave of voltage which is substantially sinusoidal and which includes at least one second half cycle, each said second half cycle of said second wave pulsating in magnitude from an initial to a final value, each said wave having frequency and phase and magnitude characteristics, one of said characteristics of said second wave being of different magnitude than the comparable characteristic Of said first wave, second means providing first and second initiating signals to control the operation of said first means whereby said first and second waves may be provided, and third means operable when said first means is providing one of its said waves to prevent said second means from causing said first means to provide the other of its said stepped waves until the magnitude of said half cycle of the said wave then being provided reaches its said final value.

5. The combination of claim 4 in which said second means always causes the initiation of the operation of said first and second means at its said initial value.

6. The combination of claim 5 in which said initial and final values are of the same magnitude.

7. The combination of claim 5 in which said waves are voltage quantities and said initial and final values are of a magnitude equal to one-half of the geometric sum of the maximum voltages at successive said first waves and successive said second waves.

8. In an intelligence transmitting apparatus, first means for generating either a first or a second stepped wave of voltage, second means controlling said first means, said second means having a first operating condition in which said first means is conditioned to provide said first sine wave, said second means having a second operating condition in which said first means is conditioned to provide said second sine wave, and third means preventing a change in the said wave which is being generated by said first means except when the said wave which is being generated by said first means is substantially at its 180* or at its 360* interval. 9 . The combination of claim 8 in which the waves generated by said first means are of different phase from the waves generated by said second means.
