A fluidic modulator having a body forming a flow aperture between an inlet and an outlet, the flow aperture having a nominal diameter less than the inlet diameter and the outlet diameter whereby the flow aperture provides a constriction to a fluid flowing axially from the inlet to the outlet, and a moveable portion operable to alter the flow aperture. To create a modulated pressure pulse the moveable portion may be for example radially shifted in the flow aperture, rotated in the flow aperture, or the rotation of the moveable portion in the flow aperture may be controlled.
