Challenge Problems
Push your limits with challenges.
Question 1
A digital audio recording relies on an A/D converter that can sample at 50 kHz. If the acquisition and aperture times are not optimized to minimize total time, how might this affect the quality of the recording?
💡 Hint: Think about what it means to sample an audio waveform accurately.
Question 2
Consider an engineer tasked with designing an A/D converter for a high-speed application. What measures could be taken to minimize aperture and acquisition times to enhance performance?
💡 Hint: Focus on material and design techniques that enhance speed.
