SIGNAL GENERATOR FOR ELECTROMAGNETIC SURVEYING |
| 摘要 |
<p>To perform an electromagnetic (EM) surveying of a subterranean structure, a signal generator produces a signal having an analog continuous waveform without steps in the waveform. An antenna is responsive to the signal having the analog continuous waveform to emit an EM field to produce the EM surveying of the subterranean structure.</p> |
