This feature can be used to suppress pilot carriers. With certain approximation you can define fixed transmission zeros.There is a special least-p optimization algorithm included. You can add an allpass to the minimum phase filter. Only QuickFil can design better group delay response.QuickFil helps you design filter of a higher quality. You can specify parametric band pass filters, which are interesting for filters having minimum number of inductors.Only QuickFil finds the circuits with minimum elements of an elliptical filter, systematically.Only QuickFil has Bessel and modified Bessel approximations, that are very easy to design, since you can define the stop band edge frequency.Just define the shape of the stop band and the program will optimize the position of the transmission zeros. Only QuickFil can easy design equal ripple or maximally flat pass band response and arbitrary stop band.You will find the most important information to the specific topic. Only QuickFil checks the inputs fields and shows some important parameter in real-time, during your input. ![]() This feature is possible due to the high speed design algorithm. No waist of time with negative components. Only QuickFil searches for realizable circuit, systematically.Paragraphic EQ Another variation on the graphic EQ. Sweep EQ This is very similar to a band-pass filter, but with variable center frequency, and no control over the width of the filter response (Q). Quasi-parametric EQ This is just another form of parametric EQ but without the bandwidth control. Only QuickFil uses special designed fast mathematical algorithms and arithmetic routines in assembler language (speed up to 5 times). Most parametric filters have shelving parameters.QuickFil is the fastest passive filter design software on the market. Proportional Parametric Equalizers have been proposed as an efficient tool for accurate magnitude response control within defined constraints. This feature can be used for matching networks. You define different terminating resistors. You can estimate the minimum quality of the filter components. The filter can be analyzed including losses (component quality Q). You will get better and cheaper components (saves money). This feature can be used to optimize your components. Variations in the filters are also possible using Norton/Impedance transformation and Pi-to-Tee conversions. You can choose the best topology concerning the mechanical limits of the filter. ![]() Reverse, dual and two-port manipulations are available. You can optimize the specifications of the filter and find a trade-off between the theoretical and the practical world.Ĭircuit topologies and values may be changed or reordered. While you are inputing your specifications, QuickFil shows you the consequences and checks if the inputs are feasible (Timesaver).ĭependent fields are updated automatically on line. The inputs are automatically checked in order to avoid program errors which are common in this field.
