Background. Logic Gate Simulator is an open-source tool for experimenting with and learning about logic gates. The simulator tool was originally designed for CIS students at South Puget Sound Community College but is free for anyone to use and modify under the GPL v3. Aug 01, 2020 · Power transformer design []. The designer first needs several known factors to design a transformer. For a transformer using a sine or square wave, one needs to know the incoming line voltage, the operating frequency, the secondary voltage(s), the secondary current(s), the permissible temperature rise, the target efficiency, the physical size one can use, and the cost limitations. How to convert binary to decimal. For binary number with n digits: d n-1 ... d 3 d 2 d 1 d 0. The decimal number is equal to the sum of binary digits (d n) times their power of 2 (2 n): This app also has 10 memories with memory contents dialog for store and recall, optional RPN Mode for better calculations. And also can solve all sorts of Factorials, permutations and combinations very easily. Physics Calculator is available here for free use.
