[QUOTE="Paul Johnson, post: 217550, member: 2643"] Sorry - I'm totally lost now. Are you making filters for audio circuits? Low cut is a frequent demand on audio, but low pass is not really something I've ever done - well, for practical music - I've clearly done it to remove the treble and leave the bass, but I don't think this is what you're trying to do. I also don;t get this 1 and -1 sample measurement? What uses 1/-1 levels. Computers tend never to go above 5v do they? That's the supply rail voltage. You're only going to get a 40V peak to peak waveform in a speaker circuit, and there's not just 40V, but serious current too? This makes me think we're talking about totally different things. What exactly are you trying to low pass? [/QUOTE]
