Abstract
A matched filter in a measurement device that includes an atomic sensor with a co-sensor is described. In one embodiment, the matched filter is a non-causal filter. Embodiments herein also describe a method for producing a matched filter by determining a filter transfer function from the transfer functions of the atomic sensor and the co-sensor. The method can be used to produce a matched filter that is non-causal but can also generate a causal filter for time sensitive applications.
