A sound signal is digitized. Sampling is performed at Time 1 through Time 5 in the
figure below, and four-level quantization is performed; in other words, the levels
closest to the sampling point are selected. After that, two-bit encoding is performed.
The result is “11 01 00 10 11”. When digitization is performed in the same way,
which of the following figures represents the sound signal that results in “01 00 10 11
01”?A sound signal is digitized. Sampling is performed at Time 1 through Time 5 in the
