solving numerically nonlinear equation
I think you need to create your own code for that. You can use the simple Rectangular Method for numerical integration. If it doesn't work very well, try the Gauss-Quadrature method. -------------------------------- Emmanuel A. Gonzalez, E.C.E.- emmgon

Matlab function block in simulink
Hi there. There is a block in Simulink called the S-Function block where you define the number of inputs and outputs. In order to use this block, you need first to develop a script using MATLAB Language and save it in an m-file. Then call the m-file into the S-Function block. Try to consider the...- emmgon

Need a voltage regulator/converter... for a TTL line ckt
Yes you need an inverter. But I am wondering that is the filter bank for? What signal are you going to input into the SP8T switch? -------------------------------- Emmanuel A. Gonzalez, E.C.E.- emmgon

Variable Power Supply
Hi there. I like the previous suggestion. Its a good idea to use an FET and control it with LabView. -------------------------------- Emmanuel A. Gonzalez, E.C.E. ECE Department De La Salle University - Manila- emmgon

DC Basics help
Grizzman, I think it is very impossible to have a capacitor-charging circuit that can provide power to a fan for five minutes. I agree with most of the respondents. Try to learn how to use the 555 timer IC. This chip is very easy to use and is very cheap. You just need to add some capacitors and...- emmgon

Variable Power Supply
With an input voltage which is less than the required output voltage, the circuit might be very tricky. It is impossible to use the usual LM317X and 78XX series because they require input voltages which is greater than the required output voltage (usually 2.5V higher). If you want to produce an...- emmgon

cheap voltage reference over temperature
You can try first building a simple zener voltage regulator circuit, which may cost around less than 10 cents and try to see if your circuit will work in the range of temperatures you are concerned of. How many volts is your reference voltage?- emmgon
