EE ToolKit PRO vs Circuit Laboratory HD

This is the brand-new Electronics Engineering ToolKit PRO! The HIGHLY RATED and RECOMMENDED productivity app. Users say it is the BEST and MOST PRACTICAL Electronics App in the whole iTunes App Store. From an electronics enthusiast with a master's degree in Electronics Engineering. This App is for engineers, students and hobbyists and anyone interested in Electronics Engineering. The App gets CONSTANT and POWERFUL improvements! !!! This is a UNIVERSAL App - for iPhone and iPad !!! 100% PRO from the beginning without any In-App purchase! The EE ToolKit PRO is the preferred Electronics App at schools and universities. It is available through the Volume Purchase Program with a discount for educational institutions. Many students, teachers and professors have downloaded the App and are using it during their studies and career. WHAT OTHER USERS ARE SAYING: “Awesome app, constant and powerful improvements” This app was worth every penny I paid for it back when I bought it years ago. Since then, I’ve regularly used it at work and found it to be an excellent, quick tool to use. The most impressive aspect of this app are the constant and VERY impressive updates! Massive feature additions and very easy to use interface! The list of capabilities this app has makes it an amazing value for truly anyone involved in electronics. “Latest version makes this an exceptional tool” The EE Toolkit was always a very useful tool, but with the additions in the latest version it is truly an exceptional tool. The author is extremely diligent in managing bugs and improving the tool. “A superb app highly recommended” Fantastic application. Very useful. Always updated. Good developer. Lots of great bonus tools. Just love it. "Incredible useful, worth the money" I have had this app for a while now. Originally as an Electrical Engineering student I didnt really use it but once I was out in the field it became my bible. I definitely recommend to any engineering students/professionals alike. I also recommend buying the Pro version because it is definitely worth it.

Circuit Lab HD is an electronic circuit analysis tool based on the modified node analysis method. It uses the same models of Spice. Four kind of analysis may be conducted: - DC: linear and non linear circuits with continuous voltage and current sources; - AC: linear and non linear circuits with sinusoidal voltage and current sources; - Multifrequency AC Analysis: linear and non linear circuits with sinusoidal voltage and current sources. It allows to analyze the circuit behavior in a range of frequencies. Useful to study the bandwidth of the circuit; - Transient: linear and non linear circuits, with sinusoidal and pulse voltage sources. User can graphically draw the circuit dragging and dropping components, then the circuit can be analyzed. Circuit may be controlled by means of the following gestures: - Drag: to move the circuit into the desired position - Tap on a component: to modify the component's parameters - Pinch: to zoom in and out - Double finger double Tap: to reset position and zoom level to the original values Tapping DC button, user gets voltage at each circuit's node. Tapping AC button, user gets voltage phasors at each circuit node or the bode graph of the voltage at each circuit node (see 06 BJT - Common Emitter). User can select the desired phasors to get the related graphs which may be controlled by means of the following gestures: - Drag: To move the chart in the desired position; - Pinch: To enlarge or shrinks the graph; - Double Tap with two fingers to restore the position and zoom level to the original values. Tapping Transient button, user can analyze circuit's behavior during time and get graphs of voltages and currents function of time. These graphs may be controlled by means of the following gestures: - Drag: To move the chart in the desired position; - Pinch: To enlarge or shrinks the graph; - Double Tap with two fingers to restore the position and zoom level to the original values. Moreover, user can enable a mobile cursor to read the values ​​in the different points of time (tap on the graph to display the cursor, tap to remove it and move it to read the values​​). Each circuit can contain: - Resistors - Capacitors - Inductors - Mutual coupled inductors - Independent sinusoidal voltage generators - Independent voltage pulse generators (with which you can also generate square, triangular and sawtooth waves); - Independent sinusoidal current generators - Controlled voltage generators - Controlled current generators - Operation Amplifier - Diodes - Zener Diodes - NPN and PNP Bjts - Channel-N and Channel-P JFet - Channel-N and Channel-P Mosfet In addition, there are the following measuring instruments: - Voltmeter; - Ammeter. User can manage his own components library to store most used components. For each component, a short video is available to demonstrate how to insert it into the circuit and edit it's characteristics. In addition, there are some more detailed video tutorials to learn how to use the application. Circuits may be easily stored and reused. User can print: - Circuits and component's list - Transient Analysis graphs (the mobile cursor is also printed if visible) Circuits can be easily shared through iCloud, by mail in the internal format so that can be reused by other users (on iPhone too) and in PDF format and they are compatible with Circuit Lab for Mac.
