In figure shown i have developed 25 level inverter whose output is distorted sine wave means full of unwanted harmonics, for filtering out these harmonics I wanna attach an active power filter (APF) at the output of inverter . For the design of APF I need pure sine wave whose amplitude is equal to the amplitude of distorted power signal, I extracted the amplitude of distorted power signal as shown in figure. Now I want to give this amplitude as input signal to another block who will generate a pure sine wave of amplitude equal to input signal. But unfortunately I am not getting any such kind of block. Any sort of help in this regard will be appreciated. thanks

Why not use Sine Wave and multiply it with the Amplitude using Product Block? If you are using newer release, one can directly use Parameter Writer

Use Min/Max block to extract amplitude of the input signal, then use product block to multiply this amplitude with a sine wave.
