Abstract
A multipath detector circuit is in a form of a differential amplifier and has a first level dependent on strength of a received signal and a second level set to a lower level than the first level. The circuit produces a multipath level signal when the first level reduces below a threshold represented by a difference between the first level and the second level increases with an increase of the first level. The multipath detector circuit is arranged so that the threshold increases with an increase of the first level.
