Hi guys, first time post on here. Had a look at the suggested threads and couldn't find what I'm looking for... Got an assignment from College where we are asked to design two bandpass filters for a given bandwidth, one series, one parallel. Now, I know I could cascade a low and a high block to chop the frequencies out, and I understand how a pure resonant band pass or stop filter works to pass or block at resonance, but the question has thrown me a bit because I didn't know you could get pure series or pure parallel (i.e. classic RLC circuit) filters with a given bandwidth? Values given where resonant frequency at 7.5kHz and a bandwidth of 400Hz. Anyone point me in the right direction? Edit: Just read the homework help sticky! I'm not after the answers, I'm well aware the only way to understand it is to plough through it yourself. Just don't want to waste my time trying to research something that doesn't exist!
