Of course it's a digital signal. It's a PCM array. If what you mean is "the artifact isn't 'aliasing' until it finally goes through the DAC", my answer to you

Of course it's a digital signal. It's a PCM array.
If what you mean is "the artifact isn't 'aliasing' until it finally goes through the DAC", my answer to you is: that's a useless and counterproductive distinction. I inadvertently introduced an artifact into my digital signal that I cannot easily remove. That this artifact magically gains a label only once it passes through the DAC is pedantic nonsense that helps no one.
- willis936 6y agoThis is not some useless academic distinction. You are measuring an analog signal. You do not worry about aliasing in all digital systems, even if they are representing something you might typically make into an analog signal. Why would you want a digital square wave? Who knows. But aliasing is not in the digital signal.
