Deep Dive: E7F14
The correct answer is B: More taps. Which of the following would allow a digital signal processing filter to create a sharper filter response is more taps. More taps provide sharper filter response. For amateur radio operators, this is important for digital signal processing. Understanding this helps when designing filters.
Why Other Answers Are Wrong
Option A (Higher data rate): Incorrect. Higher data rate doesn't create sharper response - more taps do. Higher data rate isn't the answer. Option C (Lower Q): Incorrect. Lower Q doesn't create sharper response - more taps do. Lower Q isn't the answer. Option D (Double-precision math routines): Incorrect. Double-precision math doesn't create sharper response - more taps do. Double-precision isn't the answer.
Exam Tip
DSP filter sharper response = more taps. Think 'M'ore 'T'aps = 'M'ore 'T'ransition sharpness. More taps provide sharper filter response. Not higher data rate, not lower Q, not double-precision - just more taps.
Memory Aid
DSP filter sharper response = more taps. Think 'M'ore 'T'aps = 'S'harper. More taps provide sharper filter response. Important for digital signal processing.
Real-World Example
A digital signal processing filter creating a sharper filter response: More taps would allow this. More taps mean more filter coefficients, providing sharper transitions. This is what allows it - more taps.
