If a telephone line can carry a signal with a baud rate of 6000 and we want to transmit data at 33,600bps, how many different signal levels will be necessary? Is this how a 33,600 bps modem operates?

Solution Preview

To transmit data at 33600 bps using a signal with a baud rate of 6000, we would need to transmit 33600/6000 = 5.6 bits/baud.

This is effectively saying that we need to transmit 5.6 data bits per signal ...

Solution Summary

This solution briefly explains how the required number of different signal levels are computed and how 33,600 modem operates.

Safety, and Reliability Concerns and Risk

1(a) Are safety and reliability concerns more or less important in an embedded application when compared to a non-embedded system? Why or why not?

1(b) What is risk? Give several examples of low and high risk embedded applications. Identify several embedded applications that may either be high or low risk depending on their operating context.

2(a) You have learned that the processes of debugging, troubleshooting, and testing have similar goals, but occur at different times during a product's lifetime and process with a different set of premises. How do the strategies and goals of each of these differ?

2(b) Some say that design should be a top-down process while debug and test should be bottom-up processes. What is meant by these two processes?

3(a) Identify and discuss possible problems that might arise when data or signals must be exchanged with the outside world compared to a similar exchange inside of the processor.

3(b) What are the respective advantages and disadvantages of the asynchronous and synchronous communication modes from a reliability perspective?

4. Give several examples of devices that produce analog signals that might serve as inputs to an embedded application. What kind of signal, voltage, current, or some other type might come from such devices? Briefly explain the measurement technique used in each case.
