ABSTRACT:
An underwater survey system where the existence of a large number of multiplex signals in conjunction with a relatively poor frequency response over a long tow cable, results in a situation where the transmission of a normal 30 frames per second TV picture is impossible. The invention describes a method of transmitting a reduced bandwidth TV system where the signals are modulated on a carrier and the lower sideband used. The large signal loss at the upper frequency is compensated by equalizers, which can result in objectionable interference, when the vehicle is close to the receiving end. A remotely controlled carrier is used to minimize this interference.
