Electrical student need help

----------------------

Try reading some books on basic electronics, with plenty of schematics of theoretical and real oscillators from simple square to triangular to sinusoidal. Remember,in order to get a saw tooth (triangular) waveform you can do the integral of square wave. Look at some theory on OP-amps and what you can do with them. No one here will waste time (which sometimes translates into money ) to make the homework of a lazy student, so get to work. Reading is your friend...

Further to what GM wrote, it may help you to know that what you describe is commonly called a "function generator." You should be able to find a LOT of information about them in books, on the web, ... It took me maybe a minute to find a pretty direct answer to your question that way, but you'll LEARN a lot more if you think carefully about what's going on in the circuit.

You didn't mention what you've been exposed to already. Do you understand integrators? Feedback? Schmitt triggers (or comparators with hysteresis)? If so, you're about half way there...maybe more.

How can we set up a new newsgroup for this type of question?

The thing that bothers me about questions that include sentences like, "i need appropriate circuit diagram and the components value for this as well as the output wave form either by pspice," is that this makes it seem it isn't about learning something but about avoiding learning. Like asking someone to provide a completed page of finished homework and not even bothering to worry if an explanation is provided, too.

I agree ! It comes across that way very strongly !
