Equalizer circuit

DETAILED DESCRIPTION The present equalizer circuit retains the desirable features of the Bode network while eliminating both the disadvantages of the Bode network noted above.
For example, the present circuit can be designed to equalize for variations in loss with frequency without using any inductors.
This is a particular advantage in miniaturized circuit applications.
However, the use of inductors is not precluded in the present circuit.
Further, the equalizer of the invention has no constant insertion loss when set for zero equalization.
Another feature of the present invention is the provision of an equalizer circuit in which the number of reactive elements is one-fourth the number in a constant-resistance Bode equalizer, and one-half of that in a nonconstant-resistance Bode equalizer.
Another feature of the present invention is to provide an equalizer circuit which will have a wide application of use, including by way of example: the equalizing of transmission systems having a sloping frequency imperfection and the equalizing of a corner characteristic of a bandpass filter.
The invention possesses other objects and features of advantage, some of which of the foregoing will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of this specification.
It is to be understood, however, that variations in the showing made by the said drawing and description may be adopted within the scope of the invention as set forth in the claims.
