摘要： A data gathering system includes a plurality of remote units which are controlled from a central location. Each of the remote units is attached to a television receiver which is generally but not necessarily attached to a cable system. Each of the remote units can function to determine which of several TV modes is in use as well as to store TV channel selector data, data from an optical input device, and/or data input by viewers representative of the composition of the viewing audience. The data is stored for either later collection by a portable data collector, or for direct transmission via telephone to the central location. A video message for a TV viewer, such as a survey, may be transmitted from the central location and stored at the remote units, for later display on the TV receiver associated with the remote units. Substitution of alternate programming information may also be achieved by the central control point on selected of the remote units.

摘要： The invention is a method for pulse position modulating signals which are synchronized to clocked bit periods using a clock comprising the steps of generating two, three or n signals to mark the presence of digital ones during corresponding n time slots occurring during the same bit period. The two, three or n signals are combined into a single data channel to utilize abrupt phase changes of pulses in a carrier signal at a carrier frequency, the phase changes having a very short duration to mark the presence of digital ones only. The combination of the n signals into a single data channel comprises gating each of the n signals in a sequence of serially delayed time slots corresponding to each of the n signals during a portion of the same bit period in the single data channel during time positions reserved for unexpressed zeroes.

摘要： There is disclosed a high speed data transmission system for transmitting a binary data signal over a communications path. The binary data signal is clocked at a given period. The system comprises encoded means responsive to a binary NRZ input data signal to provide at an output an encoded digital signal having time periods greater than multiples of the clock period, whereby the encoded signal occupies a lesser effective bandwidth than the NRZ signal would occupy. There are balanced modulator means having an input responsive to the encoded signal and another input adapted to receive a carrier frequency to provide at an output a double sideband suppressed carrier signal. Coupled to the output of the balanced modulator are narrow bandwidth filtering means including first low pass and second high pass parallel filter paths each having a common input terminal coupled to the output of the modulator. The ouputs of the low and high pass filters are symmetrically combined to provide a narrow single sideband signal for transmission characterized in that transitions between binary levels in said encoded signal are manifested by distinct phase changes in said single sideband signal.

摘要： A wireless digital transmitting and receiving method and apparatus combining abrupt phase change modulation with an ultra narrow band filter to remove the sidebands, resulting in a single frequency being transmitted to carry the data. The method examines and detects the changes in the carrier product only, after filtering to remove or reduce all sidebands, to obtain a usable signal. Only a single frequency with phase changes is transmitted. An ultra narrow band filter, having a rapid rise time and near zero group delay, passes the near instantaneous modulation changes of phase in the carrier.

摘要： An improved binary data communication system employs an improved VPSK encoding procedure wherein each input data bit has a bit period of M clock periods, and the data bit polarity changes are phase shift key coded with waveform widths of M/M, M+1/M, and M+2/M bit periods wherein M is an even integer greater than 3. Each of the data bits (except the last one in an encoding cycle) is encoded in an encoding signal which switches back and forth between "1" and "0" polarities and has assigned widths representing whether or not the polarity of the data bit is changed from that of the previous data bit, and whether it is the last (M-1th) polarity change in the encoding cycle. At the receiving end, a complementary procedure is used to decode the encoded signal. For transmission, the encoded signal is filtered for higher order harmonics and integrated in order to provide a sine wave output shifted 90 degrees in phase. Upon reception, the received signal is differentiated and a zero crossover detector is used to regenerate the encoded signal for decoding. The improved encoding technique can achieve Nyquist efficiencies of 10, 12.6, and 15.3 bits/Hz-bandwidth, or higher, for M equal to 6, 8, and 10 modulation levels, respectively. The encoded signal spectrum fits typically within about 1/6 of the bandwidth of the baseband NRZ signal. The encoded signal is particularly useful for transmission at high data rates in telephone, RF modulated carriers, and other transmission systems.
摘要翻译：改进的二进制数据通信系统采用改进的VPSK编码程序，其中每个输入数据位具有M个时钟周期的位周期，并且数据位极性改变是以M / M，M + 1 / M的波形宽度编码的相移键，以及M + 2 / M比特周期，其中M是大于3的偶数整数。每个数据比特（编码周期中最后一个除外）被编码为在“1”和“1”之间来回切换的编码信号 “0”极性，并且分配了表示数据位的极性是否从先前数据位的极性改变的宽度，以及编码周期中是否是最后（M-1）个极性变化。在接收端，使用补码过程对编码信号进行解码。为了传输，编码的信号被滤波以用于更高次谐波并被积分，以便提供相位90度相位的正弦波输出。在接收时，接收的信号被区分，并且使用零交叉检测器来再生编码的信号以进行解码。改进的编码技术可以分别实现等于6,8和10个调制级别的10，12.6和15.3比特/ Hz带宽或更高的奈奎斯特效率。编码的信号频谱通常在基带NRZ信号的带宽的约1/6内。编码的信号对于在电话，RF调制载波和其他传输系统中的高数据速率的传输特别有用。

摘要： A telemetering system useful for telephone installations. A normally open switch is placed between the line and telephone set. A ringing signal permits sensing apparatus to deliver a coded message to the line between the first and second rings, and the normally open switch is closed before the second ring. Ordinarily calls are delayed for the period of one ring and calls seeking data collection are disconnected before the normally open switch closes. Alternatively data may be delivered to a station associated with the telephone set.
