1) Consider a digital multimedia transmission system. Separate audio and video coders are used to code these signals. For the transmission purpose audio and video bits are packed in packets together and transmitted over a transmission link. Each packet is 1000 bytes long that includes the header bits. The system generates a packet after every 20 ms. Calculate following values: a) Minimum data transmission rate required to support the above system. b) Calculate the minimum SNR required in dB to transmit above audio and video information if a 200 kHz transmission channel bandwidth is used. c) Calculate end to end delay to transmit a 1 MB video file over a 100 km transmission link using a 1 Mbits/sec transmission data rate. The system uses a packet size of 1000 bytes. Assume pipeline packet transmission
