Analog vs. Digital Television

Description:  In this video an analog and a digital television signal are compared. Many students today are not familiar with analog television and the problem of static. Analog television uses changes in the amplitude, frequency or phase of the radio waves to transmit information. Problems of this technology include susceptibility to interference (or static), color consistency, and a smaller image. Digital sends the information as a series of 0's and 1's that are converted into the pixels on the screen. It is difficult to find an analog television signals in the US but the radio is a great substitute.
