Abstract
PURPOSE: To economize a transmission system with a circuit equipment ratio increased by reducing crosstalk disturbance caused by a color signal component, by transmitting a color signal and a sound signal with the both superposed each other through a different circuit with a luminance signal.
CONSTITUTION: Modulator 5 at a transmitting terminal attains the balancing modulation of carrier 9 by color signals 2 and 3. After having an upper side band wave component only extracted by high-pass filter 10, the obtained chrominance carrier is superposed upon the upper part of the band of sound signal 4 by signal adder 15. The chrominance carrier signal mixed with the sound signal is transmitted by balanced couple 11, and luminance signal 1 is by a different balanced couple. Transmitted signals are amplified equivalently by line equalizer 12 and then resent by the next balanced couple. In case of multi-repeating, this process is repeated. At the receiving terminal, phase regulator 13 makes the phase of the equivalently amplified luminance signal agree with that of the chrominance carrier signal, band separator 16 separates the chrominance carrier signal from the sound signal, and demodulator 14 demodulates the color signal.
