Describe Bandwidth and Spread Spectrum Techniques

*Bandwidth

Looking at a sine wave, describe how the ROM in a DDS could use only one-fourth of the memory locations to store the sine wave look-up table.

Discuss how narrowing the bandwidth of a circuit affects the noise level

*Spread Spectrum Techniques

Describe in detail a simple data communication system that will monitor the temperature of a remote inaccessible location and display temperature on a personal computer.

Suggest a future application for spread spectrum techniques and explain why SS would be appropriate for that application.
