Title: Data transmission system
IPC: H04L5/02
Filed: 1965-03-22
Abstract: 1,107,863. Digital transmission systems. NIPPON ELECTRIC CO. Ltd. 22 March, 1965 [21 March, 1964 (2)], No. 12114/65. Heading H4P. In a binary transmission system clock pulses used in the data source are mixed with a signal from an oscillator either to provide two pilot signals whose frequency-difference is related to the clock pulses rate and which are transmitted with the data, or to provide a plurality of carrier frequencies whose frequencies are related to the clock pulse rate and which are selectively transmitted to represent the data. A combination of these two systems is illustrated. In the first embodiment, Fig. 4 (not shown), the clock pulses modulate the oscillator output and three frequencies are extracted. The upper and lower frequencies are transmitted as pilot signals and the middle frequency is modulated by the data. At the receiver filters select the pilots and the frequency difference is obtained. The latter controls a clock pulse generator whose output demodulates the received data. In the second embodiment, Figs. 5 and 6 (not shown), modulation of the oscillator provides four frequencies, the data selecting these for transmission one at a time. Single side-band is used. At the receiver the modulated data is mixed with four frequencies derived from the process of modulating the output of an oscillator with clock pulses derived from the receiver output. The output of the mixer comprises, for each signal element, a signal on one of four leads, all the signals having the same frequency. The signals are added to provide a continuous frequency signal from which a clock rate frequency is derived. By mixing the clock rate frequency with the signals on the four leads, D.C. signals on four leads are obtained, these leads feeding the receiver output.
