Why Choose This?

Why This Module Stands Out

Every feature replaces passive reading with active, hands-on understanding.

🔄

Live Simulations

Change parameters in real time and instantly see signal waveforms and spectrums respond.

📊

Signal Visualiser

Interactive time-domain and frequency-domain plots for every modulation technique.

🧪

Virtual Lab

Exercises mirror real hardware experiments — perfect for remote and hybrid learning.

🏆

Assessment Tools

Auto-graded quizzes and simulation challenges for conceptual & applied understanding.

📱

Any Device

Runs in any browser — no MATLAB, no installation, no lab hardware required.

🔔

Free Updates

All new simulations added during the license period come at zero extra cost.

👥

200-User License

Full department access — students and faculty can use the module simultaneously.

🛡

Dedicated Support

Onboarding assistance and priority email support throughout your access period.

The Experience

How You Learn Differently

A structured three-stage method that builds lasting understanding over rote memorisation.

01

Visualise

See every concept rendered as an animated, interactive diagram. Watch signals transform across stages of a communication chain in real time.

02

Experiment

Adjust carrier frequency, modulation index, noise power, and dozens of other parameters — and observe the impact instantly.

03

Understand

Complete guided challenges and assessments that confirm your understanding before moving to the next module.

Testimonials

What Faculty & Students Say

★★★★★

“The AM and FM simulators finally made my students ‘get it’. No amount of blackboard diagrams achieved what this tool did in one lab session.”

★★★★★

“As a student preparing for GATE, the BER vs SNR interactive curves gave me an intuition that solved numericals I was stuck on for weeks.”

★★★★★

“We deployed this for our entire ECE department. The admin dashboard made it easy, and the support team onboarded us in under a day.”

Pricing

One Simple Price. Complete Access.

No per-user fees. No hidden renewals. One payment unlocks 4 years for your entire department.

FAQ

Common Questions

Is this a software download or browser-based?+
Entirely browser-based — nothing to install. Works on Windows, Mac, tablets, and modern smartphones. All your students need is an internet connection.
How does the 200-user limit work?+
Up to 200 unique users can be registered under your institution’s license. Users can access the platform from any device with their login credentials. You manage users via the admin dashboard.
Will we receive a GST tax invoice?+
Yes. A proper GST invoice is issued for every purchase. You can also request a proforma invoice before payment for institutional purchase-order workflows.
What happens after the 4-year access period?+
You can renew at a discounted rate. We reach out 60 days before expiry with renewal options. No data is lost during the renewal process.
Is there a trial or demo available?+
Yes — contact us at etmantra@gmail.com to schedule a live walkthrough or request trial access to a subset of simulations.
Can content be customised for our syllabus?+
Customisation is available on request. We offer tailored module sequencing and branding options for institutions with specific curriculum requirements.
