Hello! I'm actually new here but I'm really really desperate for help. So there was this class project of ours which is to simulate and make a hardware of an oscillator that produces 3 waveforms: namely sine wave, square wave, and triangular wave. But here's the twist; we need to have variables of amplitude, frequency, and duty cycle which I don't have any idea how.
Also, we need TTL implementations and we only be using positive DC supply (like 9 volts), because having negative supply is hard for hardware implementation.
I started out with my square wave using this schematic (http://webpages.charter.net/dawill/tmoranwms/Circuits_2008/Function_Generator.gif). It produced a quite pretty square wave, but I don't have any idea on how to insert those 3 variables in this circuit though and it uses 12 V as the DC source.
Can someone help me with this one please? I need some enlightenment as to how will this be done
Thank you so much!
