3,4 please Q1. A non-periodic composite signal contains frequencies from 5 to 40 KHz. The peak amplitude is 10V for the lowest and the highest signals and is 30 V for the 20-KHz signal. Assuming that theamplitudes change gradually from the minimum to the maximum and then maximum to the minimum,draw the frequency spectrum.Q2. A signal travels from point X to point Y. At point X, the signal power is 100 W. At point Y, thepower is 80 W. What is the attenuation in decibels?Q3. A line has a signal-to-noise ratio of 2000 and a bandwidth of 12000 KHz. What is the maximumdata rate supported by this line?Q4: What is the total delay (latency) for a frame of size 6 million bits that is being sent on a link with 5routers each having a queuing time of 5 us and a processing time of 2 us. The length of the link is 3000Km. The speed of light inside the link is 2 x 10^8 m/s. The link has a bandwidth of 10 Mbps. Whichcomponent of the total delay is dominant? Which one is negligible?

with regard to it regarding to it, The frequency range of the non-periodic composite signal is 5 to…
