Information

The example Cauer Filter is a low-pass-filter of the fifth order. It is realized using an analog network with operational amplifiers. The voltage source V is the input voltage (step), and the OP5.out.v is the filter output voltage. The pulse response is calculated.

This model is identical to the CauerLowPassAnalog example, but inverting. To get the same response as that of the CauerLowPassAnalog example, a negative voltage step is used as input.

The simulation end time should be 60. Please plot both V.v (which is the inverted input voltage) and OP5.p.v (output voltage). Compare this result with the CauerLowPassAnalog result.

During translation some warnings are issued concerning resistor values (Value=-1 not in range [0,1e100]). Do not worry about it. The negative values are o.k.
