| Abstract: | In the light of the actual requirements for sending the borehle signal and depth signal inan ultrasonic analogue logging to the microcomputer for processing,the working principle ofthe borehole signal data collection is discussed and the operating time sequence of the double-memory working in real time together with a 12-bit A/D converter is described.By demodu-lating the depth signal,a method for demodulating the 4-FSK signal is proposed. |
