Product Code : SCL-CE-12535
Indian Lab Suppliers supplies the Analog Signal Sampling and Reconstruction Trainer (Product ID: 12535), part of the Communication Equipment range under Laboratory equipment, a self-contained, classic-era training board for the study of the Sampling Theorem using Pulse Amplitude Modulation, requiring a dual-trace external oscilloscope.
Note on naming: this is a classic-era analog board built around natural-sampling, flat-top-sampling and sample-and-hold PAM modulator circuits, requiring a dual-trace external oscilloscope, distinct from our Sampling and Reconstruction Trainer (Product ID 12489), part of our DDS-based digital communication trainer family with a built-in signal generator and onboard audio input/output (microphone and speaker). Please confirm the exact model with our team if you are comparing the two.
Quick Answer
This trainer lets students study the Sampling Theorem using Pulse Amplitude Modulation and Demodulation: generating a PAM signal by modulating an audio signal via natural sampling, flat-top sampling, and a sample-and-hold circuit, and demodulating each using a low-pass filter to reconstruct the original sine wave.
Key Features
AF signal generator for the modulating signal · sampling clock generator providing the sampling clock and gate pulse · modulator circuit supporting flat-top, natural and sample-and-hold sampling · demodulator circuit to reconstruct the input sine wave · ±15V DC at 100 mA and 5V DC at 100 mA, IC-regulated internal power supplies · mains ON/OFF switch, fuse and jewel light · 4 mm spring-loaded stackable patch cords, half-metre length · terminals/sockets on the panel for connections and waveform observation · detailed operating instructions covering object, theory, design procedure, report suggestions and book references.
