A device for shaping harmonic oscillations with fixed phase shift in frequency range basing on a phase four-terminal device comprises a first in series connected RCchain, first parallel RCand second parallel-connected RCchain, outputs of the first series RCchain and first parallel RCchain are connected to output terminal of first , the phase four-terminal device, which is connected to a global bus (grounding) by means of RCchain. Additionally, first and second analogue converter built on operation amplifiers are incorporated in the device, a first and second non-inverting scale amplifiers and a second phase four-terminal deviceOutput of first R'C'chain of the second phase four-terminal device and output of first parallel R'C'chain of the second phase four-terminal device are connected with output terminal the second phase four-terminal device, which via second parallel R'C'chain of the second phase four-terminal device are connected to a global bus (grounding).Output of analogue convertor is connected to input of first series RCchain of the first phase four-terminal device, output of second analogue convertor is connected to first parallel RCchain of the first phase four-terminal device and first parallel R'C'chain of the second phase four-terminal device ara connected to device input terminal. Output terminals of first and second four-terminal device via first and second non-inverting scale amplifiers are connected to output terminals of the device, correspondingly. |
