Abstract
A drilling system includes a sensor, an encoder operably connected to the sensor and a pressure pulse generator operably connected to the encoder. The pressure pulse generator is configured to produce a primary signal in response to input from the encoder. The drilling system further includes a primary transducer, a reference transducer and a signal processor connected to the primary transducer and the reference transducer. The signal processor includes a two-stage filter that is configured to extract the primary signal from noise observed at the primary transducer.
