1. Which type of signal is a more exact and precise representation of its source? Explain. 2. Which type of signal is a more efficient way to send information? Explain.
3. If all transmission methods have limited bandwidth, what advantage do you think a digital signal has over an analog signal. Explain.
4. Suppose the analog signal shown is from a music signal on the radio. How do you think the music would be affected by the noise when you listen to it on the radio? Explain.
5. Think about what you have learned about analog and digital signals and their different characteristics. Do you think digital signals are affected by noise the same way that analog signals are affected by noise? Explain why or why not?
