Describe how data is represented when an analog medium is used.
What will be an ideal response?
When an analog medium is used to transmit digital data (such as through the telephone system with a modem), the digital data may be represented by various forms of a carrier-modulated signal. Two forms of carrier modulation are amplitude modulation and frequency-shift keying. In amplitude modulation, the digital data controls the presence of a fixed-frequency carrier signal. In frequency-shift keying, the 0s and 1s are assigned two different frequencies, resulting in a shift in carrier frequency when the data changes from 0 to 1 or from 1 to 0. A third method is called phase-shift keying, in which the digital data controls the phase shift of the carrier signal.
