CA 2411425
A plurality of frequency conversion sections is provided, each of which comprises a first frequency mixer for converting the frequency of the input frequency signal by a signal from a first oscillator; a first filter for extracting an element signal from the output signal of the first frequency mixer; a second frequency mixer for converting the frequency of the output signal from the first filter by a signal from a second oscillator; and a second filter for extracting a element signal from the output signal of the second frequency mixer. The respective frequencies of the first and second oscillators are determined in accordance with a predetermined frequency setting rule specified by the relationship between the frequency conversion sections. The element signals sequentially arranged in a predetermined frequency interval can be rearranged in a desired frequency interval within a desired frequency bandwidth.
