Abstract
A system and method are provided for producing controlled vibrations within a borehole. In one example, the system includes an encoder plate having a first surface, an anvil plate having a second surface, a movement mechanism configured to enable translational movement of the encoder plate relative to the anvil plate to allow the first surface to repeatedly impact the second surface to produce a plurality of vibration beats, and a vibration control mechanism configured to selectively control an amplitude of the vibration beats to encode information therein.
