Abstract
Disclosed are systems and methods related to a noise reduction device employing an analog filter and a corresponding inverse digital filter. The combination and placement of the filters within the systems aids in reducing noise introduced by processing the signal. In some embodiments, the combination of filters may also provide for increased flexibility when de-embedding device under test (DUT) link attenuation at higher frequencies. Further, the filters are adjustable, via a controller, to obtain an increased signal to noise ratio (SNR) relative to a signal channel lacking the combination of filters. Additional embodiments may be disclosed and/or claimed herein.
