Above-the-loosening prevention device in Kostas loop

摘要

this design is the input signal of the frequency of the loop play in yaw in a phase clock (Phase lock). the protection circuit on the. in the play the loop input signal with the phase of the carrier recovery can not be on the right. to extract. therefore, this research is the first to help the time and temperature will be in accordance with the frequency of the input signal, a yaw about the phase locking of the phenomenon is due to the failure of carrier recovery in a bit error (bit reeor) to eliminate the frequency shift type, basically uc788uc73c the signal also can be processed by the receiver, automatic frequency calibration circuit functional requirements "can be effective.
