3. Microwave frequency range between 108 to 1010 Hz. What is its associated wavelength?
4.
(i). Suppose a digitized TV picture is to be transmitted from a source that uses a
matrix of 480x500 pixels, where each pixel take one of 32 intensity values. If 30
pictures are sent per second, calculate the source data rate in bps. (1 point)
(ii). Assume that the TV picture is to be transmitted over a channel with 4.5 MHz
bandwidth and 35 dB signal-to-noise ratio. Find the data rate of the channel in
bps. (please show your work clearly)
5. A digitized signal is required to operate at 9600 bps. It the signal encodes a 4-bit word,
what is the minimum required bandwidth assuming the channel is noiseless.
Thank you in advance and please happy if you left the reference.
