Design RC, RL, and RLC filters (2nd–7th order) with Butterworth & Chebyshev alignments, passive crossovers, RLC band-pass/reject, and Twin-T notch—enter specs to instantly get component values and quick Bode insights in a clean, offline-friendly, dark-mode UI for lab, classroom, and audio/embedded work. What you can design: -RC & RL filters: low-pass / high-pass, 2nd–7th order -RLC filters: band-pass & band-reject (notch) -Butterworth: maximally flat magnitude -Chebyshev: ripple-tuned sharpness -Twin-T notch: precise mains or tone suppression -Passive crossovers: 2-way/3-way starter calculations Built for engineers, hobbyist and students, it turns specs into trustworthy parts fast—so you can prototype smarter, learn by tweaking, and move from idea to BOM with confidence.

Filtroscope permet de tracer des circuits de filtres électroniques et d'en obtenir automatiquement : • la fonction de transfert (expression littérale), • le diagramme de Bode (gain et phase), • la réponse en amplitude, • une visualisation à l'oscilloscope des signaux d'entrée et de sortie. Idéal pour les étudiants en CPGE et en Licence, et pour les enseignants de physique. 100 % hors-ligne, sans publicité, sans collecte de données : tous les calculs s'effectuent sur votre appareil.

Verdict
The clearest difference is in-app purchases: Filtroscope at none against Filter Calculator's 1. Filtroscope also leads on ads (none vs shown) and update cadence (daily vs every 5 months). On price, device support and iOS requirement there is nothing between them.
