Recently I announced that National Instruments<\/a> has released a set of example labs<\/a> designed to show you how you can get the full use of your Analog Discovery 2<\/a>. If you have since forgotten and want to review the summaries and mission of the seven labs, you can check out the original post here<\/a>.<\/p>\n

Over the next few weeks I’ll be covering each lab, the tools it uses, and concepts that can help you teach your students. In my previous post I went over Lab 4: Full Wave Rectifiers. In this post I’ll be going over Lab 5: Amplitude Modulation and Demodulation.<\/p>\n

<\/a>
Lab 5 is designed for an introduction to communications courses.<\/figcaption><\/figure>\n

Lab 5: Modulation and Demodulation <\/strong>is designed to give students an introduction to communication theory. Students will investigate classical amplitude modulation theory in both the time and frequency domains, learn about the basic properties of fast Fourier transforms (FFT), and see how modulation index affects AM signals in time and frequency domains.\u00a0<\/span><\/p>\n

This lab utilizes 2 sets of software,\u00a0WaveForms 2015<\/a>\u00a0and LabVIEW<\/a>.<\/p>\n

LabVIEW<\/a> is a development environment design specifically to accelerate the productivity of engineers and scientists. It features a graphical programming syntax that makes it simple to visualize, create, and code engineering systems.<\/p>\n

Waveforms 2015<\/a> is the software that drives the Analog Discovery 2<\/a>. For this lab, students will use the waveform generator to send an AM signal, and the oscilloscope to view and analyze the results in the time domain. Then they will use the spectrum analyzer to view the frequency components of the signals and the FFT.<\/p>\n

Lab 5 uses the Oscilloscope and Waveform Generator to generate and analyze signals in the time domain. It also uses the Spectrum Analyzer to analyze signals in the frequency domain.<\/figcaption><\/figure>\n
