  • Automatic frequency control system
    Patent number: 5155466
    Abstract: An automatic frequency control system applicable to home automation system and electronic appliances requiring precise frequency, comprising a resonance transmitter, a carrier transmitter, a frequency detector, highest and lowest limit oscillators for generating highest and lowest limit frequencies, a comparator including first and second phase comparators, and a resistance varying unit. The system provides the precise frequency to the electronic appliances by detecting the frequency of the data transmitted to power lines, comparing by the comparator the transmission frequency with the highest and lowest limit frequencies and decreasing or increasing the resistance of the resistance varying unit depending upon the compared resultant.
