Hi Paul, What kind of 1 Hz low pass filter gives the result shown in "received waveform after filtering" the third image? The rate of change of the edges is greater than 1 Hz. Regards, Edgar Moonah,
None, except maybe after a sample and hold. But how else to graph a set of 10 voltage samples? I couldn't think of a better way. Suggestions welcome! -- Paul Nicholson --
Hi Paul, OK, the image is to show an idea not the result of passing the signal through a low pass filter. Thank you for your reply. Regards, Edgar Moonah, Tasmania.
