Electronics Tools

Made by electrical engineers and hobbyists for electrical engineers and hobbyists, Electronics Tools provides solutions to a wide range of circuit calculations. From the basics (Ohm’s Law) to the more complex (8th order active filters), Electronics Tools has you covered with a clean and straight forward interface that provides the information you need. For instance, suppose you wanted to find the values needed for a simple second order active filter. Entering just the frequency finds the optimum resistor and capacitor values in five tolerance bands and gives you the minimum and maximum corner frequencies for each tolerance. Optionally, you can enter additional values, such as the resistor value, and the remaining values will be calculated. Every calculation provides the information that you need to know when working with your circuits. On smaller screens such as an iPhone, the calculation results can be fully displayed by tapping the “Show” button. The display can also be split showing the data entry area and its schematic along with a scrolling partial view of the results.
