DEVICE FOR SEPARATING NARROW FREQUENCY BANDS FROM A COMPLEX SIGNAL,
Abstract
Devices are known for the separation of narrow frequency bands from a complex signal, made in form of several filtering cells, tuned to the separated frequencies. The basic defidiency of such installations consists in the origination of phase displacements between the and out put voltages. The device described differs from the known ones by the use of band elimination filters and distribution elements, forming a narrow band amplifier. This amplifier assures zero phase displacement on a tuning frequency of the band elimination filter. At any frequency phase displacement does not exceed =90 degrees. (Author)
