Analog Signal Sampling and Reconstruction
Product Code : JA-CT-1507
The analog signal sampling and reconstruction trainer demonstrates the sampling theorem using pulse amplitude modulation. Students generate PAM signals from an audio signal by natural sampling, flat-top sampling and a sample-and-hold circuit, and reconstruct the sine wave input with a low pass filter, using built-in ±15 V and +5 V supplies, an AF generator and a sampling clock (SKU JA-CT-1507).
