Test your understanding of analog interfacing with 5 practice questions.
Practice Questions
Question 1
When designing an embedded system, what is the most critical factor to consider when selecting an Analog-to-Digital Converter (ADC) for a high-precision sensor application?
Question 2
A Digital-to-Analog Converter (DAC) is used to control a motor's speed. If the DAC has a 10-bit resolution and a reference voltage of $5 \text{ V}$, what is the maximum possible output voltage step size (LSB voltage) that can be achieved?
Question 3
In a system where a thermistor's resistance changes with temperature, what type of signal conditioning circuit would be most appropriate to convert this resistance change into a linear voltage suitable for an ADC?
Question 4
An embedded system is designed to measure seismic activity using an accelerometer. The accelerometer produces a signal with significant high-frequency noise. Before digitizing this signal, what is the most effective anti-aliasing technique to implement?
Question 5
Consider a scenario where an embedded system needs to precisely control the intensity of an LED using a Digital-to-Analog Converter (DAC). If the DAC has a non-monotonic error, what is the practical implication for the LED control?
