Which of the following is an advantage of a digital signal processing (DSP) filter compared to an analog filter?
A wide range of filter bandwidths and shapes can be created✓الإجابة الصحيحة
Fewer digital components are required
Mixing products are greatly reduced
The DSP filter is much more effective at VHF frequencies
الشرح
A DSP filter's response is set by numerical coefficients rather than by physical parts, so bandwidth and shape can be changed in software without touching hardware. Analog filters need different physical components for each response.
