Induct- Used by radio amateurs to calculate transformers and inductances. Transfor- Allows radio amateurs to calculate power supply transformers assembled on magnetic cores of various shapes made of electrical steel (L-, W-, O-shaped and armored), having up to 99 windings and saving the calculation results to a file OptLowpass- can be used to calculate the low-pass filter of the output stage, and there are a lot of other nice featuresįilter Solution- an excellent program for calculating almost all types of filtersįilter OU- Calculation of active filters based on operational amplifiers RFSimm99- used for calculations and modeling of range, bandpass, low-pass filters, high-pass filters Quarz- Calculation program for quartz ladder filtersĪct-fltr- The "Active filter" program allows you to calculate an active transistor filter Therefore, the resistance of losses in installation can be neglected. Short, thick conductors should be used inside the acoustic device.
The resistance of the wire that connects the amplifier to the speaker system is not calculated in this case, because it is not part of the “filter-head” circuit under consideration. The calculation method is based on the theory that both heads in the separation band have identical and purely active resistances.
The program's reference materials contain recommendations for calculating crossovers and provide calculation formulas. Speaker filter- This amateur radio program is used to calculate six options for crossovers - passive filters in acoustic systems.
