Bbox is a free quality program for designing active (opamp) passive (rlc (crossover) filters. It also has different calculators. Below is a list of calculations made by the program.
Active filter design options: Highpass 12db, Highpass 18db, Highpass 24db, Lowpass 12db, Lowpass 18db, Lowpass 24db, EQ for URPS
Passive filter design options: Lowpass 6db, Lowpass 12db, Lowpass 18db, Lowpass 24db, Highpass 6db, Highpass 12db, Highpass 18db, Highpass 24db, R-C, R-L-C, Level lowering, Impedance compensation, Filter simulation
Enclosure cabinet options: Vent/closed Box (ventilation), Bandpass, Basshorn, Transmissionline, URPS (under resonance principle subwoofer), CHP/VHP
Options section
This section contains different calculations, series resistor calculation to make leds at high voltages and “mhup/spl” calculation that I don’t understand. I guess in new versions this section will be developed and different calculators will be added.
dynamic calculations
The program has English and German language options and versions that run on Windows-PocketPC-MSDOS. You will not have much difficulty as it performs many calculations on a visual diagram. Also, it may be useful for you to make a different program or for some of your works, given the explanation of the formulas used in the calculations in the Help/KnowHow/Formula menu. .

Active Filter Design Program and Filter Application
Active Filter Design Application by Texas Instruments, prepared by the active filter design program is free, but free is pretty advanced though the company was great 🙂
Design types: high pass (high-pass), low pass (low-pass), band pass, notch, wide band pass, band reject
Frequency settings can be made according to the settings data snapshot looks graphically In its statement there (dB, Hz, kHz, USA) filter selection according to application circuit are given circuit usually 1-2 opamp based on optically as being the schematic and other information is given for the use is not difficult not to get confused if necessary detailed information
