Webwp, wsfloat Passband and stopband edge frequencies. For digital filters, these are in the same units as fs. By default, fs is 2 half-cycles/sample, so these are normalized from 0 to 1, where 1 is the Nyquist frequency. ( wp and ws are thus in half-cycles / sample.) For example: Lowpass: wp = 0.2, ws = 0.3 Highpass: wp = 0.3, ws = 0.2 http://www.ece.uah.edu/courses/ee426/Butterworth.pdf WebFree essays, homework help, flashcards, research papers, book reports, term papers, history, science, politics maryland black ice camp
