Analog-to-Digital Converters

In this lab, students will identify the pertinent parameters of an ADC and of signal acquisition. They will measure an analog value represented as a 12-bit number and convert that raw digital value to a voltage. Additionally, they will experiment with the sampling rate of the ADC and investigate the raw digital output of the ADC and the timing and shape of data coming from the ADC.

This is lab 9 of 17 in the course, Measurements and Instrumentation.

LEARNING OBJECTIVES


After completing this lab, students will be able to:
  1. Use the analog-to-digital converter (ADC) embedded in your NI Automated Measurements Board to convert an analog signal to a digital signal
  2. Revisit the resolution and sampling rate of a signal acquistion and experience its impact on an ADC converstion
  3. Use the Logic Analyzer Soft Front Panel (SFP) to observe and understand the ADC protocol
 

REQUIRED SKILLS

 
  • Basic proficiency using LabVIEW
  • Basic proficiency using ELVIS III Instruments
  • Basic knowledge of components and their behaviors

NI ELVIS III

Engineering laboratory solution for project-based learning that combines instrumentation and embedded design with a web-driven experience, delivering a greater understanding of engineering fundamentals and system design.

Automated Measurements Board for NI ELVIS III

An application board for NI ELVIS III that provides students with a experimental platform for understanding and designing a signal chain for sensor integration.

LabVIEW

LabVIEW is systems engineering software for applications that require test, measurement, and control with rapid access to hardware and data insights.
