Specific DB Scales

Since we so often rescale our signals to suit various needs (avoiding overflow, reducing quantization noise, making a nicer plot, etc.), there seems to be little point in worrying about what the dB reference is–we simply choose it implicitly when we rescale to obtain signal values in the range we want to see. Nevertheless, a few specific dB scales are worth knowing about.
