ABSTRACT:
A frequency conversion system for converting high to low frequencies. The system comprises a first frequency dividing means for frequency dividing the frequency of an input signal into 1/MN of the same, a voltage controlled oscillator, a second frequency dividing means for frequency dividing the output frequency of the voltage controlled oscillator into 1/(N + 1) of the same, a phase detector for controlling the voltage controlled oscillator such that the frequencies of the respective outputs of the first and second frequency dividing means are equal to one another, and means for sampling the input signal by using the output frequency of the voltage controlled oscillator to lower the frequency of the input signal to 1/N thereof.
