Hi please help, I get confused more and more as I search on how to design a Speech Filter. For my Signal Processing class project, we are asked to design a Speech Filter, which will have a low pass and high pass filters between 300Hz to 3KHz. But, as I look around on how to design this filter, I encounter Op-amps, Butterworth filters, fourth-order filters, etc.. which made it more complicated and more confusing. I've been reading schematics and youtube videos online - everything seems not to grasp of how to begin the approach of designing this filter. Please help! Thanks in advance!
