Pulse Width Modulation and Demodulation Manufacturer,Supplier and Exporter in India
Product Code : EL-CT-1498
Jlab Export is a leading Pulse Width Modulation and Demodulation Manufacturer,and suppliers in India
Pulse Width Modulation and Demodulation (code EL-CT-1498) is a pulse modulation trainer on which a sinusoidal signal modulates a pulse carrier to give a pulse width modulated (PWM) signal, and the PWM signal is then demodulated to obtain the modulating signal again. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Pulse Width Modulation Trainer Used For?
Pulse width modulation keeps the height and repetition rate of the carrier pulses fixed and changes how long each pulse lasts, in step with the instantaneous value of the modulating signal. Because the average value of a PWM wave rises and falls with the pulse width, filtering out the pulse frequency leaves the original sine wave. The same idea drives motor speed controllers, switching power supplies and class-D audio amplifiers, so the experiment connects communication theory with circuits students meet again in power electronics. The operating instructions set out the object, theory, design procedure, report suggestions and book references.
What to Specify When Ordering
- Number of trainers — how many PWM boards the lab needs.
- Mains at the installation — the trainer runs on 230 V ±10%, 50 Hz AC, so check that your supply matches.
- Other pulse modulation boards — the PAM, PPM and combined PPM/PWM trainers below are separate items and can be quoted together.
Frequently Asked Questions
How do PWM, PAM and PPM differ?
All three modulate a train of pulses but change a different property. Pulse amplitude modulation varies the height of each pulse, pulse width modulation varies its duration, and pulse position modulation shifts its timing. JLab makes separate trainers for PAM and PPM, linked below.
Which accessories come with the trainer, and what else is needed?
Patch cords are provided in adequate number, each stackable from the rear at both ends with 4 mm spring-loaded plugs and half a metre long. A 20 MHz cathode ray oscilloscope is required as well; it is a separate item, and the Dual Trace Oscilloscope linked below can join the same quotation.
How does it differ from the Pulse Position and Pulse Width Modulation trainer?
That trainer studies both pulse position and pulse width modulation and is housed in an ABS plastic cabinet. This one covers PWM modulation and demodulation, with a ±6 V DC, 100 mA IC regulated supply.
What should an export enquiry contain?
The number of trainers, the destination country and port or city, the delivery terms required (for example FOB or CIF), any packing or labelling needs, and the tender reference if one applies.
Who manufactures this trainer?
JLab (Jain Laboratory Instruments Pvt Ltd) builds it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of electronics and communication trainers, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The PWM trainer comes from JLab’s own works rather than from a trading house, so colleges, dealers and importers buy from the maker, and repeat orders and spares are supplied by the same works. JLab exports worldwide and ships to buyers in every region — for example the Netherlands in Western Europe, Kuwait in the Middle East, Malaysia in Southeast Asia, South Africa in Southern Africa and DR Congo in Central Africa. See the JLab lab tenders page for tender enquiries.
Other Pulse Modulation Trainers
- Pulse Position and Pulse Width Modulation — a compact PPM and PWM trainer in an ABS plastic cabinet.
- Pulse Position Modulation and Demodulation — a panel with an AF sine wave oscillator and an RF oscillator for pulse position modulation.
- Pulse Amplitude Modulation and Demodulation — samples a sine wave audio signal into PAM and shows how the sampling rate affects distortion.
- Dual Trace Oscilloscope — 20 MHz, dual channel, cathode ray tube.
All models are listed in the Communication Trainer range under Electronics Lab Equipments.
