When analog information is converted to digital data, we must consider two properties that affect the exactness of the digital representation, one from sampling and one from quantizing. which of the following is from sampling?

Sampling rate

A pixel that can have only one of two possible color values requires 1 bits to store the color information.

True

Converting from analog to digital involves a two-step process: sampling and quantization.

True

Our everyday decimal numbering system is base 10. Computers use base 2, which is also known as the binary numbering system.

True

The smallest unit in a binary system is a byte.

True

When analog information is converted to digital data, we must consider two properties that affect the exactness of the digital representation, one from sampling and one from quantizing. which of the following is a result of quantization?
