Digital-to-analog conversion is the process of changing one of the characteristics of an analog signal based on the information in digital data. Aspects of Digital-to-Analog Conversion Amplitude Shift Keying Frequency Shift Keying Phase Shift Keying Quadrature Amplitude Modulation Topics discussed in this section:

ASK is implemented by changing the amplitude of a carrier signal to reflect amplitude levels in the digital signal. For example: a digital “1” could not affect the signal, whereas a digital “0” would, by making it zero. The line encoding will determine the values of the analog waveform to reflect the digital data being carried.
