According to the FCC, 143 broadcasters have already terminated their analog signals and another 60 plan to do so before February 17.
Since a digital computer controller only recognizes zeroes and ones, it needs an A/D board to convert the analog signals into this digital form so it can use analog signals in its control scheme.
One possible way to simplify the whole procedure involves working directly with the continuous wave itself, circumventing the time-consuming and costly process of converting the analog signal into a digital form.
Then the demodulator converts the analog signals to digital signals and reduces the signals to baseband signals with central frequency at 10MHz, which are absolutely digital signals here, the MPEG decoder converts these digital signals to analog signals, the analog signals here are still interlaced scanning signals which will become progressive scanning signals after the interpolation algorithm of back-end image processing.
Despite the stunning clarity of an HDTV video image, more than 80 percent of all TV content is still transmitted and received using standard definition composite analog signals, while VCRs and DVD players require analog interfaces to send video and audio signals out to the TV.
