App: FilterDesignLab-PRO
Developer: MTK-Digital
Genres: Developer Tools, Productivity

FilterDesignLab-PRO is a standalone design and simulation environment for digital Infinite and Finite Impulse Filters (IIR and FIR). It is structured into 4 views for designing the filter gain, analyzing the phase, displaying its poles and zeroes (respectively kernel), and  verifying its response by application to test signals. Adjust several discrete and continuous filter parameters in realtime and see its effects on test signals immediately. Adjustments can be done by text input, via drop-down menus, or mouse/touch input. Note that several additional features of FilterDesignLab-PRO are offered as  individual InApp purchases. The resulting filter recursion equation and the corresponding coefficients are accessible via Copy&Paste. FDL-PRO offers the generation of Swift, Matlab®, and C-Code. The design and the Code can be realized in the various numerical precisions: DOUBLE, SINGLE (FLOAT), 16Bit, and 8Bit.
