Reconfigurable annular filtering device

The invention discloses a reconfigurable annular filtering device. A first adjusting device, a filtering device and bias voltage sources are ingeniously combined and applied to ensure that a user candirectly adjust the bias voltage sources by adjusting the first adjusting device. The filtering device can achieve the expected filtering effect, and the use convenience of the annular filtering device is improved. 本发明公开了一种可重构环形滤波装置。对第一调节装置与滤波装置和多个偏置电压源进行了巧妙的结合与应用，确保使用人员可直接通过调节第一调节装置，对多个偏置电压源进行调节，使该滤波装置达到预期的滤波效果，提高环形滤波装置的使用便捷性。
