Foenics - FPI's - Frequency-Removal
The Frequency-Removal FPI is a highly efficient tool for the precise attenuation of small frequency bands, and can be used to remove constant tones and other artefacts.
Eight independent high quality notch filters are implemented, and can easily be used by choosing the center frequency, bandwidth and the desired attenuation. The ability to listen to the removed signal passages in real-time allows easy adjustments, and ensures the maximal signal integrity retained by avoiding the elimination of uncorrupted 'information' by the forensic analyst.
A further simplification of the adjustments can be achieved by using the Frequency-Removal 'Auto' mode, defining the recommended bandwidth automatically.
