Abstract
The object is to simplify the configuration of a filter in a reception apparatus. The reception apparatus includes a filter. The filter provided in the reception apparatus selects a signal transmission characteristic that is one of a band stop characteristic or a low pass characteristic. Further, selection of the signal transmission characteristic in the filter provided in the reception apparatus is performed in response to a desired signal and an interference signal. In the filter provided in the reception apparatus, passage of the desired signal and attenuation of the interference signal based on the selected signal transmission characteristic are executed.
Claims10
A reception apparatus, comprising:
- a control circuit configured to compare a difference, between a frequency of a desired signal and a central frequency of an interference signal, and a specific threshold value;
- and
- a filter configured to:
- select one of a band stop characteristic or a low pass characteristic as a signal transmission characteristic of the filter based on a result of the comparison,
- set, based on the selection of the band stop characteristic, a first frequency of the filter, wherein the first frequency is between an upper limit for a band of the frequency of the desired signal and the central frequency of the interference signal, and
- set, based on the selection of the low pass characteristic, a second frequency of the filter, wherein the second frequency is higher than the upper limit for the band of the frequency of the desired signal.
