I am not sure why you have posted images (as I gather they are) in "pdf" format. It is rather inconvenient to view them as it tends to require software other than the browser. Pdf is generally used for printable documentation, which this does not appear to be, or obfuscation, which annoys many here.
A .jpg or .png makes it much easier to view - and answer accordingly.
You really should explain the curious use of "square wave" and "carrier" in the same description.
