Data Acquisition Toolbox

Analog Input Examples

This section illustrates how to perform basic data acquisition tasks using analog input subsystems and the Data Acquisition Toolbox. For most data acquisition applications, you must follow these basic steps:

1. Install and connect the components of your data acquisition hardware. At a minimum, this involves connecting a sensor to a plug-in or external data acquisition device.
2. Configure your data acquisition session. This involves creating a device object, adding channels, setting property values, and using specific functions to acquire data.
3. Analyze the acquired data using MATLAB.

Simple data acquisition applications using a sound card and a National Instruments board are given below.
