This schematic shows a General Purpose (2nd-Order) as well as a Medium-Size EQ, each with a 1-Channel - Double-Precision algorithm grown by 2. The schematic includes an input block and terminals for completion of signal flow.
The configuration produces the following frequency responses, with the red line the General Purpose filter and the green line the Medium-Size EQ:
This schematic uses the General (2nd-Order / Lookup / Slew) block, a counter, an input and two output blocks.
A Butterworth lowpass filter with 4 curves is selected. For them the index range possible is 0 - 3, and curve 2 uses index 1.
This schematic uses the State-Variable block, with a Stimulus, Probe, input and three output blocks.
The frequency response produced, showing the three LP, HP, and BP filters, is:
This schematic uses the Text-In Filter (linked) and Text-In Filter (Unlinked) with probe and stimuli blocks. Linked has 1-ch - double-precision grown by 2, which behaves as a series filter, while Unlinked has 1-ch - double-precision added by 2, which behaves as a parallel filter. Tone (lookup/sine) is the input; T connection and terminals complete the signal flow.
The frequency response:
