Latest Patents

De Haan's latest patents include a color television recording system employing frequency modulation. This system is designed for transmitting a color television signal, specifically for recording on and subsequently reproducing from a record carrier. The color television signal to be transmitted contains a first carrier that is frequency-modulated with the luminance information and a second carrier that is modulated with the chrominance information. The frequency of the second carrier lies between zero and the first-order lower side band of the modulated first carrier, which corresponds to the highest modulation frequency. Notably, the second carrier does not have a fixed frequency but is locked to the instantaneous frequency of the modulated first carrier by a constant integral ratio, which is preferably two or three, depending on the characteristics of the transmission medium and the signal processing equipment.
