One of the incredible advantages of electronic circuit simulation programs is the ability to see how our circuit will behave when we change the parameter of an element in a circuit. And it’s even better if we can see on one chart the circuit response to different values of this element’s parameter. Let’s see how it is done in TINA-TI.

Lets simulate the low-pass filter circuit:

When we choose the AC Transfer Characteristic (Ctrl+ Alt+ A) we will see:

And now let’s see how our filter will behave when we change the resistor values from 800 Ω , to 100 kΩ in 20 steps. First, click the icon “select control object”:

Then click the R1 rezystor. After that a new window will open:

Click “Select” button. A next new window will open:

In our example, we fill the parameters as follows:

Then press “OK” button. After that, we start again AC Transfer Characteristic. But this time we will see the whole “family” of characteristics.
