Title:
TRANSMITTING AND RECEIVING SYSTEM AND TRANSMITTING AND RECEIVING METHOD
Document Type and Number:
Japanese Patent JP2021076474
Kind Code:
A
Abstract:
To provide a transmitting and receiving system or the like that can prevent the interference of an electromagnetic wave.SOLUTION: A transmitting and receiving system comprises: a piezoelectric material 5 as an electromagnetic wave generator; an ultrasonic transducer 31; a receiving device 32; and a control unit 24. The piezoelectric material 5 receives an ultrasonic wave and outputs an electromagnetic wave. The ultrasonic transducer 31 radiates an ultrasonic wave toward the piezoelectric material 5. The receiving device 32 receives the electromagnetic wave output from the piezoelectric material 5. The control unit 24 controls the ultrasonic transducer 31 and the receiving device 32. The control unit 24 has a spectrum diffusion circuit 41 that executes spectrum diffusion processing on a transmission signal for oscillating the ultrasonic wave, and a spectrum inverse diffusion circuit 42 that executes spectrum inverse diffusion processing on a received signal obtained by receiving the electromagnetic wave in the receiving device 32.SELECTED DRAWING: Figure 1
