Unless specified otherwise, use the free space propagation speed of light 3x108 m/s to calculate the propagation delay. For numerical calculations, the results must show the appropriate unit. Show a complete solution for each problem 3. Consider a digital multimedia transmission system. Separate audio and video coders are used to encode these signals. Audio and video bits are packed in packets together and transmitted over a transmission link. Each packet is 2,000 bytes long, which includes a 48-byte header. The system generates one packet every 40 ms. Calculate the following values: a. The minimum data transmission rate required to support the above system. b. The minimum signal-to-noise ratio (SNR) in dB required to transmit the above audio and video information. Assume a 400-kHz transmission channel bandwidth is used. c. The end-to-end packet delay over a 50-km link, using answer in Part a).
