    Hi,
    I am trying to do an AC analysis simulation.

    There are different type of sweep such as octave, decade, linear, and list.

    Does anyone know what each of these types do ?

    Can you explain in detail what is the difference between each of them ?

    Thanks in advance.

    These explain what frequency values will be used.

    An octave is a factor of 2.
    For example, an octave sweep will go through 1 Hz, 2 Hz, 4 Hz, 8 Hz etc. depending on your start / end frequencies.
    You also indicate how many points per octave to fill in the gaps.

    A decade is a factor of 10.
    Same deal as an octave but 1 Hz, 10Hz, 100 Hz, etc.

    Linear you simply give a start and end point and how many points in between.
    For example, 1 Hz through 100 Hz with 100 points will do 1, 2, 3, 4, 5 Hz etc.

    A list is where you define all the frequencies you're interested in.
    For example, you can say frequency is 10 Hz, 25 Hz, 100 Hz, 1kHz and that's all it will do.
