Exam 11: Digital Theory

Luminance and color information are sampled at the same rate.

Who first derived the rule that the sampling rate must be more than twice the highest frequency contained in the analog signals?

The larger the quantity of data, the greater the amount of bandwidth required to transmit that data. This movement of data is referred to as output.

The number of binary or digital bits the computer can read at once is known

The basis for determining the sampling rate of video was the

Noise is analog information just as video and audio are.

Digital information is variable and often changes over time.

The transfer of data from one source to another occurs through a serial digital interface.

Although not directly compatible with SDI, the Is a very common interface that allows consumer cameras, displays and computers to be used in a professional environment, even though they can only send the signal about 20 feet.

Which example below represents four times the subcarrier frequency as the sampling rate for the luminance portion of the signal, and two times the subcarrier frequency for each of the color difference signals.
