Wasn't sure where to put this -- Lowpass Filter in Excel
Ok I need some excel help, I need to model a sawtooth wave mathematically (done) and then I need to put it through a lowpass filter, but I need to do it in excel. My prof expects an excel spreadsheet, and I have no clue how to put it in there. On wolfram I use plot Ʃ[sin(2*n*pi)/(n*pi)] and that works when I take it out 100 or so terms, but excel doesn't like those kinds of functions.
How can I put it in there?
