1.) What effect does time division multiplexing have on the bandwidth requirements of a channel?

2.)A waveform travels in space at a rate of approximately 300 million meters per second. The wavelength of a sine wave is the actual distance in space that is used by one sine wave as it travels. What is the wavelength of a 100-MHz sine wave? What is the wavelength of a 500-MHz sine wave? Antennas to send and receive electromagnetic waves are often sized to be one-half of the wavelength for the particular wave being used. Compare your previous calculations to the size of VHF and UHF television antennas. How large would a 1/2 wavelength antenna have to be to transmit a 60-Hz wave?
