Sampling & Reconstruction Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-CE-12489
Indian Lab Suppliers supplies the Sampling & Reconstruction Trainer (Product ID: 12489), part of the Communication Equipment range under Laboratory equipment, a trainer that demonstrates the basic scheme used to transmit an information signal — sampling, the Nyquist criterion, sample/sample-and-hold circuitry, and signal reconstruction via low-pass filters.
Note on naming: this DDS-based trainer, part of our digital communication trainer family with a built-in signal generator and onboard audio input/output (microphone and speaker), is distinct from our simpler, classic-era Analog Signal Sampling and Reconstruction Trainer (Product ID 12535), which studies natural/flat-top/sample-and-hold PAM sampling and requires a dual-trace external oscilloscope. Please confirm the exact model with our team if you are comparing the two.
Quick Answer
This Sampling & Reconstruction Trainer covers the basic concepts of sampling and reconstruction — the Nyquist criterion, the role of the sample amplifier and the sample-and-hold amplifier, and the duty cycle of the sampling pulse while transmitting a signal — and demonstrates signal recovery using low-pass filters of different orders. It has a built-in 1 kHz (5 Vp-p) sine wave generator as an onboard signal source, plus onboard audio input and output circuits (with microphone and built-in speaker) so students can see the same process applied to a real audio signal. The aim is to transmit signals in digital form and reproduce the original information signal in analog form at the receiving end of the communication system, using the sampling and reconstruction technique.
Key Features
Crystal-controlled pulse generator · demonstrates sampling and reconstruction as per the Nyquist criterion · on-board synchronized analog signal generator · six switch-selectable sampling frequencies · switch-selectable sampling pulse duty cycle · internal/external sampling signal selectable · separate sample and sample/hold outputs available · on-board second-order and fourth-order low-pass filters · audio input and output links to show transmission and reception of a real-time audio signal.
Experiments
Study of sampling and reconstruction techniques · study of the Nyquist criterion for sampling and reconstructing a signal · study of the effect of the sample amplifier and the sample-and-hold amplifier on the reconstructed signal · study of the effect of sample/hold circuitry on the reconstructed waveform · study and comparison of the responses of 2nd-order and 4th-order low-pass filters.

Frequently Asked Questions
What sampling frequencies does the trainer support?
Six switch-selectable sampling frequencies: 20, 50, 80, 100, 200 and 400 kHz, with a switch-selectable duty cycle from 0–90% in decade steps.
Can this trainer demonstrate sampling on a real audio signal, not just the onboard generator?
Yes. Onboard audio input and output circuits, with a microphone and built-in speaker, let students apply the sampling and reconstruction process to a real-time audio signal in addition to the built-in 1 kHz sine wave generator.
What reconstruction filters are provided?
On-board 2nd-order and 4th-order Butterworth low-pass filters, each with a 3.4 kHz cut-off frequency, so students can study and compare their reconstruction responses.
Do you supply this equipment for institutional or export orders outside India?
Yes. Indian Lab Suppliers quotes equipment for institutional and tender buyers across export markets — see the Tenders page for documentation requirements.
