Title:
WIRELESS RECEIVER AND FILTER CHANGE PROGRAM
Document Type and Number:
Japanese Patent JP2021034912
Kind Code:
A
Abstract:
To easily set an appropriate bandwidth.SOLUTION: A wireless receiver comprises: a display unit including a touch panel on which a band scope indicating a frequency band of a predetermined bandwidth including a frequency of a received signal is displayed and a predetermined operation from a user is accepted; and a control unit which controls a band limiting filter to be used for demodulating the received signal. The band scope includes a spectrum display region in which at least a signal strength within the frequency band is displayed as a spectrum. The control unit performs control so that the bandwidth of the band limiting filter is displayed on the display unit while being superposed on the spectrum display region as a semi-transmission region along a frequency axis of the received signal, and controls a pass band of the band limiting filter in response to an operation that is accepted by the touch panel, to the semi-transmission region.SELECTED DRAWING: Figure 1
