Abstract
There is provided a wide band transmission system which, by using two or more filters and gain control circuits, is operated so as to determine the gain control amount of the gain control circuits according to an intensity and frequency band of a signal which is desired to be received. Further, a bias circuit increases the attenuation amount of the gain control circuit connected to the filter whose pass band is out of the band of the desired signal.
