The G$\mathrm{.}729$ audio codec is a frame$-$based codec. Both figures $5\mathrm{.}1$ and $5\mathrm{.}2$ contain $2$ G$\mathrm{.}729$ frames each.

$1)$ How big is the delay because of the coding?

$2)$ How big is the delay because of the packetizing?

$3)$ What is the net bitrate of the G$\mathrm{.}729$ codec?

$4)$ What is the gross bitrate of the G$\mathrm{.}729$ codec, if the packets are transmitted via an Ethernet interface acc. to Figure $5\mathrm{.}1?$

$5)$ How big is the delay because of packetizing, if $4$ G$\mathrm{.}729$ frames are transferred in one RTPpacket?

$6)$ What is then the gross bitrate on an Ethernet interface?
