Plot low pass filter matlab
Webb3 feb. 2016 · Are you doing a Matlab homework assignment, trying to learn filter design, or trying to get a filter implemented? If you are a practicing engineer trying to get a filter designed and implemented, you need a different type of answer. \$\endgroup\$ – Webbthis is just an addendum to jojek's answer which is more general and perfectly good when double-precision math is used. when there is less precision, there is a "cosine problem" that crops up when either the frequency in the frequency response is very low (much lower than Nyquist) and also when the resonant frequencies of the filter are very low.
