Calculate the minimum timeout value for a stop-and-wait algorithm running over a 50-meter point-to-point copper link. Assume a minimum delay of 5 µs at the receiver. If you know the distance between two points, you can calculate the speed-of-light latency, although you have to be careful because light travels across different media at different speeds: It travels at 3.0 × 108 m/s in a vacuum, 2.3 × 108 m/s in a copper cable, and 2.0 × 108 m/s in an optical fiber.

Your challenge is to use MATLAB to plot a received signal at a base station in a multipath channel when the transmitter sends a sinusoidal carrier signal. A transmitter sends a sinusoidal signal of frequency 1.5 MHz to the base station. There is a line-of-sight (LoS) path to the base station receiver, with delay 1 usec. The signal on this path is attenuated in amplitude by a factor 0.9 (the LoS amplitude gain). There are also three single bounce paths, one of delay 2 usec, with an amplitude gain of 0.5, one of delay 7 usec, with an amplitude gain of 0.4, and a third of delay 10 usec, with amplitude gain of 0.2. These parameters are fixed and do not change during the transmission. The project is to write MATLAB code to obtain the signal received at the receiver. Plot the signal over a time interval of 20 usec, including axes, and provide units for the time axis. Then answer the following questions: a) How is the output signal frequency related to the input signal frequency? b) Does the…

A PWM signal has a period of 100 millseconds. The initial pulse width is 10 millseconds. This means theresolution is 10%. True False
