    Abstract: This contribution involves the generation, transmission, propagation and selective reception of electrical, magnetic or electromagnetic energy in the form of a halfwave sinusoidal pulse signal, from one location to another, whereby intelligence input for transmission is recovered from one sinusoidal pulse, or from a plurality of sinusoidal pulses. In a transmitter embodiment, one or more sinusoidal halfwave pulse generators are provided, where each pulse signal may be generated asynchronously, with varying polarity, duration and amplitude on a continuous serial sampled information basis. Complementary pulse signal filtering and recovering of transmitted intelligence is provided in a signal receiver embodiment. Another transmitter embodiment includes a software-driven signal synthesizing capability, wherein a plurality of timed sinusoidal halfways pulses are linearly summed as elementary signal components of an information-carrying propagable signal.

Timing networks are included in the transmitter control circuit for allowing the output signals to be transmitted to the selected receiver only within a brief time interval. Reset networks are interconnected within the transmitter control circuit and the timing networks for returning the transmitter control circuit back to a condition of awaiting asynchronous commands for forwarding to a selected receiver via the single pair of wires.

    Abstract: A data modem that operates to permit the concurrent high speed transmission/reception of digital data over two independent data links or systems, is disclosed. Data bits concurrently applied to a transmitting modem from two independent data sources are interlaced to form a stream of data bits that are effectively grouped as data words to be differentially phase modulated. Modulated data may be transmitted over ordinary voice grade telephone lines to a distant receiver modem at effectively twice the bit rate of the individual data sources. Successive groups of six interlaced data bits are divided into two groups of three bits which are uniquely identified by having a selected phase angle added to or subtracted from the differential phase angle for alternate groups of three bits. The selectively added phase angle is detected at a receiving modem to identify the respective groups of three bits and thereby permit accurate distribution of demodulated data bits to the respective data utilization terminals corresponding to the two data sources.

    Abstract: Digital data transmission at a very high bit rate through randomly selected voice-grade telephone lines by the use of a transmitter which includes digital differential angle modulation; and a receiver which includes digital differential angle demodulation is disclosed. Binary data wherein the individual bits are represented by a discrete level format during bit cell times is stored in multibit groups of randomly varying data patterns. Each multibit group is converted from its digital level format to a predetermined phase level format which includes a plurality of different phase, or angle, increments. At the transmitter a divider circuit receives a high-frequency signal which is many times higher than the bit rate of the data to be transmitted, and divides it into an intermediate frequency square wave signal which is still many times higher than the bit rate. The predetermined phase levels representative of each multibit group are compared with divider output taps by a comparison circuit which selectively alters the dividing operation so that an information-representing phase-shifted intermediate frequency signal is emitted. This information-representing phase-shifted signal is filtered and translated down to a low-frequency analog signal which is passed through a narrow band pass communication link exhibiting a linear phase over the band pass width. At the receiver end of the data communication system, the narrow band pass limited signal is translated up to the intermediate frequency and a clock signal is derived from the informationrepresenting envelope. This clock signal is employed to synchronously gate a high-frequency counter output into a detector circuit which samples a precise portion of a phaseshifted signal containing the information to be ascertained. Two separate storage registers in the detector circuit receive successive counter output valves depending upon the phase sampled from the precise portion of the information-containing signal. A parallel adder determines the difference between successive counts, each count of which is characteristic of the informationrepresenting phase change originally received during the interval in question. An encoder converts the phase-change signal as emitted by the parallel adder, back to its original digital data level format.

    Abstract: An asynchronous data to clock phase scripted shift register encoder and time/phase decoder circuit with clock phase information in the shift register in the form of two clock period wide pulses or one clock period wide pulses depending on the asynchronous data being either in phase or out of phase respectively with the clock. The system enables a reduction in shift register elements by a factor of 2 to 1, maximizes the decoder gate aperture, and the time decoder is capable of determining the correct delay to within one-half a clock period while a conventional shift register decoder does so only to within one clock period.
