Objective

To develop an interactive platform that allows engineering students to perform digital signal processing experiments online, including signal generation, filtering, and transformation, with real-time visualization of signals and frequency-domain analysis.

Key Features

Student Panel:

• Generate and visualize discrete-time signals (sine, square, triangular, sawtooth)

• Apply DSP techniques such as convolution, correlation, FFT, IFFT, and filtering

• Visualize time-domain and frequency-domain representations in real-time

• Adjust signal parameters (amplitude, frequency, phase) dynamically

• Save experiments and export plots for reports

Teacher Panel:

• Create or upload DSP experiments for students

• Assign tasks and monitor student activity and results

• Provide feedback and guidance on signal analysis

• Upload reference signals and expected outputs for comparison

Admin Panel:

• Manage users (students & teachers)

• Monitor system performance and active sessions

• Add new DSP modules, signal types, or filters

• View analytics on usage patterns and student engagement
