A measurement while drilling (MWD) tool includes a sensor, an encoder operably connected to the sensor and a modulator operably connected to the encoder. The modulator includes a first stator, a rotor and a second stator. The rotor is optimally positioned between the first and second stator. The use of a second stator amplifies the pressure pulse signal produced by the modulator.
