What kind of digital signal processing audio filter is used to remove unwanted noise from a received SSB signal?
An adaptive filter✓الإجابة الصحيحة
A crystal-lattice filter
A Hilbert-transform filter
A phase-inverting filter
الشرح
An adaptive filter continuously adjusts its own coefficients from the statistics of what is arriving, separating the correlated speech components from uncorrelated noise. That lets it suppress noise and heterodynes without a fixed, predefined response.
