    Connecting the grounds of two power supplies

    HI Can the grounds of two different power supplies each supplying different voltages be connected? If not, why? And if they can... what about the theory of isolation? For instance in the case where a microprocessor operating at 5V is connected to a device using 240V, the have to be isolated...

    Guidelines and resources for DSP beginners

    Re: New to DSP Hi What I'm interested is the actual use of a DSP board. I already know about Fourier and La Place and those other topics that you find in a DSP text. However when it comes to programming and implementation I'm at a dead end. Does anyone have any suggestions on where I can find...

    how to use BJT as a DIODE

    Hi I am interested in building a rectifier using transistors instead of diodes. The transistors have to be controlled using a DSP. ( somewhat like the PWM switching of transistors in an inverter) Can the same concept of using a transistor as a diode apply?

    Looking for info about rectifiers designed using transistors

    Re: Rectifiers That sounds like an interesting suggestion. But I did an online search and didn't find anything. Any help in the area of info location? I have one other question, I'm a bit confused about something, I've never attempted to build/actually use a rectifier circuit before, I just...

    Looking for info about rectifiers designed using transistors

    Hi I know that usually diodes or SCRs are used when designing rectifiers, but I'm looking for information on rectifiers designed using transistors. Does anyone have such information or at least know where I would be able to locate the info? Thanks

    Help me with a C++ Inventory program

    c++ inventory Hi I was required to write a program to keep track of inventory for a farm. It entails the following: 1.We are required to use structures to store the name and quantity of each animal. 2. Allow the user to input a new animal (in alphabetical order) using the find function. 3...

    Function / Waveform Generator Design using op-amps

    HI Does anyone have any idea how to design a function generator using op amps to produce triangular, sine, square and ramp waveforms? I also need to design for a level shifting of ± 1V. The sine is produced by an oscillator and the square by an astable multivibrator. I'm having problems...
