摘要
By using the two square-law circuits for squaring the common mode and orthogonal components of the carrier wave and by using the multiplying circuit for multiplying these squared signals, the Costas loop carrier recovery circuit can be constituted. The carrier recovery circuit is constituted such that a phase synchronous circuit constituted by a PLL is controlled by a signal obtained by removing a sign component from an input carrier wave.
