Abstract
For a QPSK Costas loop with a constant input frequency, the phase detector characteristic is analytically computed in the pull-in range. The performance analysis of this loop is reduced to the consideration of differential equations describing the Costas loop in the phase space for proportionality-integrating loop filters.
