Abstract
An apparatus and method to improve transmission of mud pulse telemetry signals is described. A mud pulser is placed in series with a water hammer pulse valve. While generating pulse signals, the mud pulser modulates the flow of mud downstream to the pulse valve. The pulse valve, which cycles at a frequency that is proportional to the flow rate through the tool, operates at a frequency that is effectively modulated by the mud pulser. A sensor that may be at the surface receives a mud pulse signal that comprises both an amplitude modulated component as well as a frequency modulated component.
