Title:
CONVERSION DEVICE AND RECEIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/131831
Kind Code:
A1
Abstract:
An A/D conversion unit (64) samples a first analog signal corresponding to the in-phase component at a first sampling rate to generate a first digital signal, as well as samples a second analog signal corresponding to the quadrature component at the first sampling rate and at a timing different than that of the first digital signal to generate a second digital signal. A first FIR filter unit (66a) generates, on the basis of the first digital signal, a third digital signal at a second sampling rate lower than the first sampling rate. A second FIR filter unit (66b) generates, on the basis of the second digital signal, a fourth digital signal at the second sampling rate at a timing matching the third digital signal.
