5. A digital audio broadcast service is to transmit digital music. Stereo audio signals are to be transmitted using a digital modem over a data link. The specifications of the system are the following: Each audio signal is sampled at a rate of 44 kilo samples/second and quantized using 24 bits; the data link is implemented using a transmission bandwidth of 0.25 MHz. (Note that a stereo signal uses two channels). Assume a 46 byte overhead is added before the transmission of each packet.

C. Assume that the broadcast service use UDP/IP/Ethernet protocol to transmit digital audio using a packet switched network where the maximum packet size is limited to 800 byte including the combined header. Protocol header sizes are as follows; UDP: 8 byte, IP: 20 byte and Ethernet: 18 byte. Calculate the number of packets requires to transmit a 250 ms digital audio segment. Also, calculate the segment transmission delay assuming that pipeline packet transmission technique is used. The transmitter receiver separation is 200 km.

Imagine that you place your stereo speakers outside (to provide music for a party). They are places distance of 1.5 m apart along a line we will call the y axis. Imagine that both speakers are reproducing the sound of a female singer holding a solo high A (880 Hz) for several seconds consider a line parallel to the y axis but 8.0 m from it. At what points along this second line would the sound be loudest? At what...

Projecta Inc. is a Japanese manufacturer of projectors and audio equipment for cinemas and music theatres across Asia. Projecta Inc. has recently begun implementing its expansion strategy into Europe. To fund working capital for this expansion, Projecta Inc. needs €8,000,000 Euro (EUR) for nine months. The company can either borrow the €8.0m Euro in Paris at 3.5% p.a., or borrow the equivalent of €8.0m Japanese Yen (JPY) in Tokyo at an interest rate of 1.5% p.a. The current spot exchange...

Consider that you desire a digital transmission system, such that the quantization distortion of any audio source does not exceed ±2% of the peak-to-peak analog signal voltage. a. If the audio signal bandwidth and the allowable transmission bandwidth are each 4000Hz. And the sampling takes place at Nyquist rate, what value of bandwidth efficiency (bits/s/Hz) is required. b. Repeat part (a) except that the audio signal bandwidth is 20kHz (high fidelity), yet the available transmission bandwidth is still 4000Hz.
