What type of digital signal processing filter is used to generate an SSB signal?
An adaptive filter
A notch filter
A Hilbert-transform filter✓الإجابة الصحيحة
An elliptical filter
الشرح
Generating SSB by the phasing method requires a copy of the audio shifted by 90 degrees at every frequency across the passband. A Hilbert-transform filter performs exactly that wideband quadrature shift in the digital domain.
