[sdiy] Opamp Function Generator Kit.

[Yash]

I just bought a DIY kit with an OPAMP function generator. I was quite
pleased as there was also a square wave oscillator kit which was more
expensive. The one I bought gives me a Square, a Triangle and a Sine, thanks
to a  LM348N IC (quad OPAMP).

I'm thrilled, especially because after I downloaded some spec sheets about
the component, I also got some other applications like a state-variable
filter.

The circuit has the three outputs for sine, square and triangle. I think
they can be used simultaneously.

I am hoping to augment this circuit with a sawtooth as well as a noise
generator before I attack the filter part.

I believe I will strive to seek a variable state filter or a multi-mode one
for the filtering. I would prefer to have a variety of filters to be put in
series and/or parallel before the amplifer stage.

Can I also just build my filters separately without worrying too much about
eh connections between my modules?

Any ideas about the baove would be most welcome.

Regards,

Yash.
