Abstract
A two-stage filter is provided. A first stage filter performs a first stage filtering operation on an initial signal to adjust a frequency of the initial signal to output a first filtered signal. A second stage filter is connected to the first stage filter. The second stage filter performs a second stage filtering operation on the first filtered signal to filter an interference component that is generated during the first stage filtering operation from the first filtered signal to output a second filtered signal.
