RLC Filter Selector 1.0

RLC Filter Selector is a straightforward utility for designing passive analog filters quickly and confidently. Choose a topology (RC, RL, or RLC) and a target response (low‑pass, high‑pass, band‑pass, or notch), then enter your desired cutoff or center frequency and quality factor. The tool calculates practical component values and summarizes how each selection influences impedance and overall frequency response. It’s a handy companion for lab work, prototyping, and classroom exercises—useful for students, hobbyists, and professionals alike.

Key features:

• Guided workflow for common passive filter topologies
• Fast calculation of R, L, and C values from basic targets
• Clear summaries of corner frequency, Q, and attenuation
• Simple, focused interface designed to get results quickly
