Setting Y 1 = Y 2, and solving for X 2 yields X 2 = X 1 LF/H. By observation, the desired transfer function is T= LF/H. Therefore, theoretically, if x 1 (t) is passed through this filter and the resulting x 2 (t) is played on the headphones, it should produce the same signal at the eardrum. Since the filter applies only to a single ear, another ...

If, for instance a target known to be 1.5 m in height (1500 mm) is measured to 2.8 mrad in the reticle, the range can be estimated to:
