ABSTRACT:
The present invention provides an improved method for transmitting logging data from a logging apparatus operating in a well borehole to surface equipment over a logging cable. The logging data has variations in amplitude, which are converted to a frequency-modulated signal. The center frequency of the frequency-modulated signal is relocated to a lower frequency, which is within the bandwidth of the logging cable. The frequency-modulated signal is transmitted over the logging cable and received by the surface equipment, where the logging data is reconstructed.
