BIOSIGNAL PROCESSING APPARATUS AND METHOD

The invention provides a biosignal processing apparatus and a method. The biosignal processing apparatus includes a communication interface configured to receive a biosignal, and a processor configured to set a target interval of the biosignal, calculate a quality metric corresponding to the target interval based on a target component that is a frequency component of the target interval corresponding to a set value and a non-target component that is a frequency component of the target interval not corresponding to the set value, and estimate a quality of the biosignal based on the quality metric. 提供种生物信号处理设备和方法。种生物信号处理设备包括：通信接口，被配置为接收生物信号；处理器，被配置为：设置所述生物信号的目标间隔，基于目标分量和非目标分量计算与所述目标间隔相应的质量度量，并且基于所述质量度量估计所述生物信号的质量，其中，所述目标分量是对应于设置值的所述目标间隔的频率分量，所述非目标分量是不对应于所述设置值的所述目标间隔的频率分量。
