Introduction

Are you a student, engineer, or researcher looking for a reliable and user-friendly active filter designer? Look no further than Filter Wiz Lite, a free application that offers a wide range of features and capabilities to help you design and analyze filters with ease. In this article, we will explore the main features and benefits of Filter Wiz Lite, and discuss how it can be a valuable tool for anyone working with filters.

What is Filter Wiz Lite?

Filter Wiz Lite is a free active filter designer that is specifically designed for Windows users. It is a simplified version of Filter Wiz PRO, which offers advanced capabilities and sophistication. However, Filter Wiz Lite is still a powerful tool that can help you design and analyze filters with ease. It is significantly superior to other free desktop and online calculators, making it a popular choice among students, engineers, and researchers.

Main Features of Filter Wiz Lite

User-Friendly Interface

One of the key features of Filter Wiz Lite is its user-friendly interface. The application allows instant access to all completed phases of the filter design, and presents information and choices with clarity and ease of use. This makes it easy to navigate and use, even for those who are new to filter design.

Filter Types

Filter Wiz Lite allows you to design a wide range of filter types, including:

Lowpass filters: These filters allow low-frequency signals to pass through while attenuating high-frequency signals.
Highpass filters: These filters allow high-frequency signals to pass through while attenuating low-frequency signals.
Bandpass filters: These filters allow a specific range of frequencies to pass through while attenuating all other frequencies.
Bandstop filters: These filters allow all frequencies to pass through except for a specific range.

You can rapidly design order 1 to 10 active filters using Filter Wiz Lite.

Antialiasing Filter Design

Filter Wiz Lite also includes a new Antialiasing Filter design feature. This allows you to design an antialiasing lowpass filter for A/D conversion, which is essential for many digital signal processing applications.

Approximations

Filter Wiz Lite offers five different approximations, including:

Butterworth: This is a popular approximation that offers a flat frequency response and a simple design.
Chebyshev: This approximation offers a steeper roll-off and a more complex design.
Inverse Chebyshev: This approximation offers a steeper roll-off and a more complex design, but with a more gradual transition between the passband and stopband.
Elliptic: This approximation offers a steeper roll-off and a more complex design, but with a more gradual transition between the passband and stopband.
Bessel: This approximation offers a flat frequency response and a simple design, but with a more gradual transition between the passband and stopband.

Export Design as eSketch File

One of the most useful features of Filter Wiz Lite is its ability to export the design as an eSketch file. This allows you to take advantage of Schematica's eSketch simulator for further analysis, without having to redraw the schematic.

Op Amp Selector and Slew Rate Calculator Tools

Filter Wiz Lite also includes new Op Amp selector and Slew Rate Calculator tools. These tools allow you to find suitable op amp families by sorting on GBW, slew rate, or quiescent supply current. The application also includes Schematica's Resistor Color Coder, which can be useful for designing and analyzing circuits.

"Strategy" Help Windows

Finally, Filter Wiz Lite includes "Strategy" help windows that allow you to view help topics appropriate to each design phase. These help topics are accessible through "Strategy" buttons, and all help topics are also available through a standard help file.

Conclusion

In conclusion, Filter Wiz Lite is a powerful and user-friendly active filter designer that offers a wide range of features and capabilities. Its user-friendly interface, lowpass, highpass, bandpass, and bandstop filter types, Antialiasing Filter design, five approximations, export design as eSketch file, Op Amp selector and Slew Rate Calculator tools, and "Strategy" help windows make it an essential tool for anyone working with filters. Whether you are a student, engineer, or researcher, Filter Wiz Lite is a valuable resource that can help you design and analyze filters with ease.
