Description
Block Mean (Variable Frequency) calculates the average value of the signal connected to the input of the In block. The average value is calculated using a moving average equal to one cycle of the signal frequency.:
where
-
— input signal;
-
— the period is defined as , where — frequency.
This block uses a moving average. Therefore, to output the calculated average value, the block needs to complete one simulation cycle. In the first simulation cycle, the output value remains constant and corresponds to the specified initial value.
