Abstract
A method for synchronizing signals among transmitters and receivers of a logging tool positioned in a borehole is provided. Measurement signals generated from operating a transmitter in the borehole are acquired by a receiver. An operating frequency of the receiver is determined by a processing unit. The operating frequency of the receiver is different from an operating frequency of the transmitter. A sampling frequency of the receiver is determined based on the determined operating frequency. A phase delay of the receiver is determined by the processing unit. The acquired measurement signals are adjusted by the processing unit based on the determined sampling frequency and the phase delay of the receiver.
