Abstract

In a frequency converting system, an input signal x(t) is supplied to a signal branching section for dividing a predetermined frequency domain into M bands, extracting signal components of the respective divided bands. The respective signal components and local signals each including a frequency difference corresponding to a predetermined intermediate frequency with respect to a center frequency of each band are input to a frequency converting part. The signals of the respective divided bands are converted into signals of intermediate frequency bands each including the predetermined intermediate frequency as the center frequency, the conversion outputs are sampled by using a common clock signal, whereby the conversion outputs are converted into digital signals. Further, after being subjected to phase correction processing, the digital signals are subjected to frequency conversion and combination processing by a signal regeneration part.
