 So the next, let's try ICHBLPF (Inverse Chebychev IIR Low Pass Filter).
Choose the component and place it.
Double-click on ICHBLPF and change its parameters. Cutoff Frequency is
3500 and Stop Band Ripple is 50.
And please open a monitor for ICHBLPF.
Then you can see the reduction ratio at 3500Hz is -50dB. Understand that
Inverse Chebychev LPF has Stop Band Ripple but the reduction ratio never
goes higher than -50dB after 3500Hz.
If you want its coefficients, please choose "Tools" -> "Save
Coefficients" on the menu.
See the coefficients, block diagram and transfer function.
