1. (45%)Please draw a block diagram of a digital communication system.
2. (20%)According to North American Analog TV (NAA-TV) protocol, a picture is
divided into 525 horizontal lines, which constitute a frame. Each frame is
525 horizontal lines, decomposed into two 262.5 line interlaced fields.
Completion of each interlace field takes 1/60 second.
Hence, 30 still pictures are shown per second.
Horizontal line-scanning frequency is 262.5/(1/60) = 15.75 KH
Consider a sinusoidal signal with random phase, defined by
X(t) = A cos(2 fc t + )
where A and fc are constants and is a random variable that is uniformly
distributed over the interval [- , ], that is,
f ( ) =
