How can I calculate a mean of a signal or a mean of a part of a signal on Simulink ?

Hello everyone,

Will you help me to calculate a mean of a signal (mean of a part of a signal) on Simulink ?

I tried with the block " mean" but I always find the same input signal. I want a value ( the mean value of the signal).

thank you in advance

Hello @karim,

To calculate the mean of a signal, follow the steps listed below:

1. You can use the “Mean” block from the Simulink Library.
2. After placing this block in the appropriate place in the model, double-click on the block. A window will open named “Block Parameters: Mean”.
3. Specify the fundamental frequency. This parameter defines the part of the signal for which you need the mean. For example, if you want the mean of half a cycle of a sine signal, specify (2 * fundamental frequency) as the frequency.
4. Then, connect this block to a “Display” block, which will provide the desired scalar value.

You can refer the documentation for more information. To refer the documentation, follow the listed steps:

1. Right click on the target block.
2. Click on the last option Help.
