Analog-to-Digital Converters

This is lab 9 of 17 in the course

by Enable Education

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.

LEARNING OBJECTIVES

After completing this lab, students will be able to:

Use the analog-to-digital converter (ADC) embedded in your NI Automated Measurements Board to convert an analog signal to a digital signal
Revisit the resolution and sampling rate of a signal acquistion and experience its impact on an ADC converstion
Use the Logic Analyzer Soft Front Panel (SFP) to observe and understand the ADC protocol
