$1-$Sound may be modeled as sinusoidal functions. Compare the relative frequency and

wavelength of musical notes. Use $343\frac{m}{s}$ as the speed of sound and the following!

frequencies for the musical scale. $($Points $4)$

$2-$For multipoint configuration, only one device at a time can transmit. Why? $(4$ Point$)$

$3-$ What is the wavelength of an FM radio station that broadcasts at $99\mathrm{.}5$ MHz $?$ Round your answer to two decimal places. $(2$ Point$)$

$4-$ A digital Video Camera provides an uncompressed output provide a signal resolution of $720480$ pixels at a frame rate of $30$ fps and $16-$bit quantization for each pixel $(4$ points$)$

a$.$ What is the required bandwidth for the transmission of uncompressed video stream? $2$ points $(5$ points$)$

b$.$ How much data storage space is needed to store three mint videos $(5$ points$)$
