thanks for you help but you haven't suggested a chip that is capable of this. 'I learned this when i was taking my degree' i am looking for a chipset that allows me to change the pitch at a frequency between the aforementioned, if you don't know of any, just say so. otherwise is there somebody...
I have looked all over the place for this chip(Texas Instruments ICS76477), it's like trying to find lord lucan riding shergar on our back fields. Sorry if this post is in the wrong place but once found, I want to share the project which involves this chip in the hobbies section of EDA. Does...
That's it, by the looks of it, thx mate. Is there any schematics for this anywhere? I will look but if you know of a PWM schematic it would save time. Thx again it is definitely where I need to be this.
The NE566N only goes upto 1Mhz, I am looking to go between 1 and 10Mhz. I have 20K trimming pot, so that could work for the resistance aspect. The control voltage would be the way to go on a square wave. Do I even need the LM741? it does help on unwanted oscillations. It needs higher MHz tho!
I have a little problem with a design which I have followed. I am novice at this really but have put a circuit board(Breadboard) together to send pulses through a water cell I have designed. My main problem is the frequency cycles being achieved, they are 20khz I believe, I want to achieve 1 to...
