This letter gives an analysis of a transparent CCPLL in the presence of noise. The analysis is based on geometrical considerations and is an extension of the well known geometric method for the analysis of FM signals in the presence of noise. The main result obtained here is that the phases of the separated (demodulated) FM signals are accompanied by a sequence of random «clicks». The level and rate of occurrence of these clicks depend on the «transparency» of the PLLs used in the CCPLL system
