waveform generator ic
Hi,
i was just wondering if someone could help me with something im trying to build..
i am looking for a simple circuit diagram for a waveform generator, battery powered, can switch between sine/triangle/square waves and is variable from 1Hz to about 1kHz - or something that is kinda similar that i can change the components to achieve the desired frequencies..
i've found some diagrams for ones that range from 1Hz to 1MHz, but as i want it so i can play around with audio frequencies, the range is too great.. is changing the frequency range as simple as changing the value of the potentiometer to one that ranges from 1k Ohm to 1M Ohm and capacitor to 1uF thus giving a range from 1 ≤ f ≤ 1000 (f=1/RC) or would there be more involved in changing an existing diagram?
ultimately i'd like to make two of these that run at the same time so i can play around with destructive interferences and things, but ill be happy with just making this to start with!
as for my electronics experience, i used to play around with simple kits when i was little and i did a 6 month course in electronics in middle high-school, but aside from soldering techniques and a few things about ohms law and such, i've forgotten most of it..
alright, any help would be greatly appreciated..
thanks
