Document Type and Number:
Japanese Patent JP2021076739
Kind Code:
A
Abstract:
To provide a signal processing device capable of reducing missing of a signal in a low-frequency range when performing signal processing.SOLUTION: A signal processing system includes a signal processing device having a signal processing section which performs processing so that a first signal as a signal included in a frequency band of a transmission object and a second signal as a signal having a frequency in a frequency band lower than the frequency band are included in the frequency band; and a signal processing device including an expansion section which performs processing so that a frequency band of an input signal is lowered below the frequency band, and an output section which outputs at least one of a signal corresponding to the frequency band from the processed signals and the signal having the band lower than the frequency band.SELECTED DRAWING: Figure 1
