Product Code : SCL-CE-12525
Indian Lab Suppliers supplies the Pulse Amplitude Modulation and Demodulation (PAM) Trainer (Product ID: 12525), part of the Communication Equipment range under Laboratory equipment, an entry-level, operational-amplifier-based training board for the study of Pulse Amplitude Modulation and Demodulation.
Note on naming: this is a simpler, entry-level board built around an operational-amplifier PAM modulator and a point-contact-diode demodulator, requiring an external oscilloscope, distinct from our DDS-based PAM Modulation and Demodulation Trainer (Product ID 12507), which uses an on-board digital signal generator, SMD LED indicators and a 2nd-order Butterworth filter. Please confirm the exact model with our team if you are comparing the two.
Quick Answer
This trainer lets students demonstrate sampling of a sine wave audio signal to produce a Pulse Amplitude Modulated (PAM) signal, demodulate the PAM signal to recover the original audio signal, and observe how sampling rate affects distortion in the recovered signal, using a variable-frequency sampling pulse generator and an op-amp-based PAM modulator.
Key Features
Variable-frequency sampling pulse generator · sine wave audio frequency modulating signal generator · PAM modulator circuit based on an operational amplifier · PAM demodulator circuit based on a point-contact diode and an operational amplifier · ±9V DC, 100 mA, IC-regulated internal power supply · mains ON/OFF switch, fuse and jewel light · 2 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.
