    摘要： An adaptive filter circuit for filtering and attenuating signals coupled thereto which includes first and second opposite conductivity transistors having base electrodes coupled together and emitter electrodes coupled together. The first and second transistors are operative to conduct in response to portions of the signal coupled thereto in excess of a predetermined amplitude. A filter network is coupled to the first and second transistors and has a first predetermined attenuation characteristic when the transistors are non-conductive and a second predetermined attenuation characteristic when the transistors are conductive.
