A modulation device includes: a communication unit; and a controller configured to: divide a communication signal received by the communication unit into a plurality of frequency bands, determine at least one noise band including a noise signal among the plurality of frequency bands, and generate an output signal by replacing at least one of the plurality of frequency bands corresponding to the noise band with another frequency band.

Modulation device, controlling method of modulation device and vehicle

An audio system includes: a receiver receiving a first broadcast signal corresponding to a frequency selected by a user; a controller comparing a signal strength of the first broadcast signal in a first broadcast band to a signal strength of the first broadcast signal in a second frequency band and determining which frequency band of the first and second frequency bands has a higher signal strength based on the comparison; and a signal processor generating a second broadcast signal by changing a phase of the first broadcast signal in the determined frequency band, and generating a third broadcast signal in the determined frequency band canceled by synthesizing the first and second broadcast signals.
