ADC and Sampling

In this lab students will learn how analog signals from sensors are converted into a digital signal using analog-to-digital conversion (ADC). Students will also learn about elements of ADC such as sampling and Nyquist frequency. Through the process, students will complete hands-on activities and answer questions to confirm their understanding.
This is lab 3 of 9 in the course, Measurements and Instrumentation.

LEARNING OBJECTIVES


After completing this lab, students will be able to:
  1. Discuss the process of analog to digital conversion, and the effects of resolution and range on the measured signal
  2. Discuss the complexity of sampling theory, including multiplexing and Nyquist frequency.
  3. Identify the minimum resolution, sampling rate, and range required for the given measurement scenario.
