1. Express a period of 100 ms in microseconds.
2. The period of a signal is 100 ms. What is its frequency in kilohertz?
3. A sine wave is offset 1/6 cycle with respect to time O. What is its phase in degrees and radians?
4. If a periodic signal is decomposed into five sine waves with frequencies of 100, 300, 500, 700, and 900 Hz, what is its bandwidth? Draw the spectrum, assuming all components have a maximum amplitude of 10 V.
5. A periodic signal has a bandwidth of 20 Hz. The highest frequency is 60 Hz. What is the lowest frequency? Draw the spectrum if the signal contains all frequencies of the same amplitude.
