In particular, not all epimorphisms are surjective in the classes CAn of n-dimensional cylindric algebras and the class of representable algebras in CAn for finite n > 1, solving Problem 10 of (28)

Therefore, a novel IPMSG system using a well-designed phase locked-loop circuit (PLL) and interface filters is proposed. Owing to introducing the two devices, the PLL and interface filters, the direction of the quadrature axis of the
