SamplingStudio

DEMO:

Introduction:

A desktop application to illustrate and visualize signal sampling and recovery, aliasing and sampling error.

Core Features:

Signal Sampling:

Load, visualize, and sample a mid-length signal (approx. 1000 points).

Display sampling frequency in both actual and normalized forms (0×fmax to 4×fmax).

Reconstruction:

Recover the original signal using three methods: Whittaker-Shannon , DB-3 Wavelet, and Zero-order interpolation

Four interactive graphs for:

Original Signal: Shows sampled points as markers.

Reconstructed Signal: Displays the recovered signal.

Error Visualization: Displays the difference between original and reconstructed signals.

Frequency Domain Analysis: Identifies aliasing effects.

Signal Composer:

Load signals from files or compose signals using a built-in mixer.

Add multiple sinusoidal components with adjustable frequencies and magnitudes.

Modify or remove signal components dynamically.

Additive Noise Control:

Add noise to the signal with customizable Signal-to-Noise Ratio (SNR).

Visualize the impact of noise on different signal frequencies.

Real-Time Updates:

All changes in sampling, recovery, and noise adjustments update in real-time.

Pre-Prepared Testing Scenarios:

Three example signals demonstrating different sampling scenarios.
