WebThe second part of this project included the development of an active noise cancellation circuit capable of performing variable frequency noise attenuation. Developed using the LabView platform, the designed circuit was tested on multiple noise samples, each of different varying amplitude, frequency, and length. WebA slowness adaptive f-k filter reduces signal distortion and improves the attenuation characteristics of the filter. The technique uses a time‐ and space‐variant narrow reject‐band f-k filter. Optionally, coherent noise is compressed before application of the filter. The apparent slowness of coherent noise events is estimated using local ...
