HIGHSH (High Shelving Filter)

This component is a High Shelving Filter (1st order IIR filter). Double-click on it and click "Change Parameters" to set parameters. You can "shelve" frequencies higher than Fc. Positive G shelves the gain up and negative G shelves it down. S decides how sharp the slope is. Left-click to select it and right-click to choose "Open a Monitor". The characteristics of the filter is drawn on the monitor window. (This example has Negative G) "View" -> "Scale Change" on the menu to change the scale. You can save the coefficients by choosing "Tools" -> "Save Coefficients" on the menu. Sample Schematics Coming Soon...
