Q1. A system requires a D/A converter that can produce an output step size no larger than 0.1% of the full‑scale voltage. Which minimum resolution in bits satisfies this requirement?
💡 Difficulty: easy | ✅ Correct: B
Q2. A motor‑control loop uses a 12‑bit D/A converter with a specified settling time of 5 µs. If the control algorithm updates the output every 8 µs, will the converter meet the timing requirement?
💡 Difficulty: medium | ✅ Correct: B
Q3. A microcontroller uses an 8257 DMA controller to transfer a waveform buffer of 2048 samples to a 10‑bit D/A converter at a rate of 250 kS/s. Which DMA configuration ensures continuous output without underrun?
💡 Difficulty: hard | ✅ Correct: C
