ABSTRACT:
A bandpass and/or elimination filter network for electric signals, includes an input circuit (1) which has the capacity to symmetrize and adapt the input impedance, and two branches (B C) and (D E) to which two frequency dependent cells (L C) are introduced. The branches meet at a combination circuit (2) for convergence to the sole output. This network can be used in communications electronics applications.
