Hello,
I am currently in college and working on a final project. It is a 5-channel color organ made up of 5 active filters (opamp sallen-key filters to specify). This may seem like a stupid question but if these filters are of unity gain, do the opamps need a DC supply voltage? If so, how do I determine the DC supply voltage to use?
Thanks in advance
