9.8.3 Lowpass and Highpass Filters

Using firpm function of MATLAB, design a lowpass and a highpass filter to filter
out highpass and lowpass components of DTMF tones, respectively. Do not use very
high-order FIR filters.

1. Lowpass filter:
a. Filter out the highpass component of the signal you generated through the
lowpass filter designed by firpm. Note: You should use convolution not FFT
b. Plot a couple of periods of the output signal
c. Plot the spectrum of the output signal, comment on the spectrum
2. Highpass filter: Repeat (a,b,c) for the highpass filter

A 200 km, 2.5 Gb/s communication link consists of four spans and three optical amplifiers. The transmitter power is 0 dBm and the fiber loss is 0.25 dB/km. Assume the receiver bandwidth ∆f = 0.7B and responsivity of 0.8 A/W. The operating wavelength is 1.55 µm.
a) What is the span loss? What is the optimal amplifier gain for maximum SNR?
b) If each amplifier has a 4 dB noise figure, then what is the SNR at the output of the last amplifier?
c) Whatis the receiver sensitivity (Q=6)? Will the system work as designed?

Consider a residential network that connects to the internet with a DSL link that has a download rate of 4 Mb/s. Assume that there are three UDP flows sharing the link and the remote hosts are sending at rates of 1 Mb/s, 2 Mb/s and 3 Mb/s. Assume that the ISP router has a link buffer that can hold 300 packets (assume all packets have the same length).

a) For each flow, what fraction of the packets it sends are discarded?

b) For each flow, about how many packets does it have in the queue.

c) Now, suppose the queue at the ISP router is replaced by three queues that can each hold 100 packets and that the queues are scheduled using weighted-fair queueing, where the weights are all 0.33. In this case, what fraction of packets are discarded from each flow?

d) How many packets does each flow have in the queue?

e) Now, suppose the weights are 0.2 for the first flow, 0.6 for the second and 0.2 for the third. In this case, what fraction of packets are discarded from each flow?

f) How many packets does each flow have in the queue?
