We are pleased to announce the long awaited arrival of FilterShop^™ 3.0. This large and ambitious undertaking spanned four years of R&D resulting in hundreds of thousands of lines of source code.

"FilterShop was a dream that has become a reality." said Chris N. Strahm, President of Research and Development for LinearX. "The goal was to produce a comprehensive professional development tool that seamlessly integrates both analog and digital filter design requirements."

The product features: rich graphical user interface, true analog circuit synthesis, a massive target generation system, powerful target and circuit optimization, advanced digital filter design for both IIR and FIR filters, analog filters to 32 poles/zeros, mixed analog/digital filter design, switched-capacitor filter design, comprehensive equalizer design using potentiometer tapers, custom circuit entry/editing with proprietary circuit components, frequency domain analysis, time domain analysis, and noise analysis.

Filter design is an integral part of all fields of electronics R&D. Applications abound in many fields including audio, general purpose DSP, instrumentation, communications, aviation/navigation, digital radar, biomedical, telephony, etc.
