WINLPF (FIR Low Pass Filter by Window Function Algorithm) |
This component is an FIR LPF designed by Window Function Algorithm. Double-click on it and click "Change Parameters" to set parameters. Tap Count is up to 400 and Kaiser Window Constant decides how sharp the slope is. (See this tutorial) Left-click to select it and right-click to choose "Open a Monitor". The characteristics of FIR filter is drawn on the monitor window. "View" -> "Scale Change" on the menu to change the scale. You can save the coefficients by choosing "Tools" -> "Save Coefficients" on the menu.
