FilterRC is a streamlined utility designed for electronics engineers, students, and hobbyists to accurately model and analyze passive RC (Resistor-Capacitor) filters. Whether you are designing a circuit for audio processing, signal conditioning, or noise reduction, FilterRC provides the analytical tools needed to optimize your design in seconds.
Comprehensive Filter Modeling Easily toggle between Low-Pass and High-Pass topologies. Simply input your component values to determine the exact cutoff frequency ($f_{-3dB}$). The app handles the calculations instantly, allowing you to iterate through different component combinations rapidly.

Advanced Technical Insights Go beyond basic frequency calculations. FilterRC provides essential electrical metrics for every design:
• Time Constant ($\tau$): View the exact charging and discharging characteristics of your circuit.
• Capacitive Reactance ($X_C$): Understand the resistance offered by the capacitor at the specific cutoff point.

Dynamic Visualizations Gain a deeper understanding of your circuit's behavior with built-in plotting tools:
• Bode Plot: Visualize the magnitude response (dB) across a wide frequency spectrum to identify the passband and roll-off rate.
• Phase Plot: Analyze the phase shift between input and output signals to determine signal lag or lead across various frequencies.

Session Management Never lose track of your work. FilterRC includes a built-in history log that automatically saves your calculations. Access a dashboard of your design history to compare different sessions, view your most used topologies, and manage your saved records.
Optimized Workflow
• Default Values: Start with standard component values to see immediate results upon launch.
• Professional Interface: A focused, distraction-free environment tailored for technical work.
• Theme Flexibility: Choose between Light, Dark, or System Default themes to suit your working environment.

Designed for precision and ease of use, FilterRC is the essential companion for anyone working with passive RC circuits. Perform calculations, analyze frequency responses, and refine your electronic designs with professional tools.
