Question#3 (5 Marks)
Consider a periodic signal which
is decomposed into seven sine waves with frequencies 300, 200, 1000, 600, 800,
700 and 400 Hz; what is the Bandwidth of this signal? Give your answer in
proper units with complete calculations.

Question#4: (5 Marks)
A work station is transmitting
data at a rate of 1.69 Mbps over a channel which gets affected by a sudden
noise. If the noise occurs for duration of 0.01 msec (milliseconds); how many
bits are going to be impacted by this burst error? Give your answer in proper
units with complete calculations.
