[TRANSISTOR ATTENUATOR?]

Hi prateeksikka

I may even generalize that voltage at any point in a circuit can never exceed the supply! Smiley

Nearly correct but consider what happens when an inductance suddenly loses its current  ;D

[Conversion of square wave to sine wave]

Hi MP

So let's start helping people out when they ask a question...

Couldn't agree more, one of the more pleasant aspects of this community is the relative lack of FLAMERS and the helpful attitude of most of the people involved.

Remember, searching things out does not come easy to all

Whilst English is the common language here, it should be remembered that not everyone has it as a first language or that they have years of computer experience behind them.

Thanks, just pointing him in the right direction

Hi ebena

as a starter, remember that a square wave can be constructed from an infinite number of sine waves, therefore in theory a suitably narrow band filter will be *all* that is necessary

[PIC information]

Hi Jade

There is a wealth of information available on the web about PIC's...

The first place to look for information on a specific PIC is Microchips website http://www.microchip.com

If you are a beginner with PIC's then here is an place to start http://o.webring.com/hub?ring=picmicro

Perhaps you could be more specific about the explanations you require

[Need Ic which can Enable Its outputs One by One!]

Hi again

Or alternatively, you could use a series of flip-flops with common clock/clear and Q output taken to D input of next flip-flop

[Need Ic which can Enable Its outputs One by One!]

Hi Shahriar

Looks like an ideal and simple job for a PIC - perhaps 16F84?, Port A 8 bits, Port B 5 bits.

Hi

The two pictures don't show up, can you repost

[new idea.. help~~]

Hi birdbird,

can I suggest a very good starting point for you, which is to read a book call "Who is Fourier?" (ISBN 0-9643504-0-8) which is an introduction to Fourier transforms but more importantly builds up to an understanding of the subject based on the differences between sounds.

Best of Luck
