Curves of the second order play an important role in solving of constructive geometric modeling problems. The search for theoretical generalizations allows us to develop algorithms to solve various problems of projective geometry from unified theoretical positions. However, some wellestablished
concepts, such as the center curve of the second order, in the current interpretation impedes the development of unified algorithms. The research material shows, that the contradictions
can be eliminated in a new interpretation of definition of the conic curve center.

Reducing the processed data in the device processing of radar signals is an important task, despite the increasing performance of computing devices. The limiting case of reducing the bit depth quantization is binary. Binary quantization has a number of drawbacks. The inherent disadvantages of binary quantization is proposed to compensate for the introduction of third-level quantization. Examined statistical characteristics of signals at the output of the ideal limiter with dead zone.
