The correct option is A Digital to analog modulation
Digital to analog
modulation is the process of changing the characteristics of an analog signal
based on the information on a digital signal.
Digital-to-analog
conversion is the process of changing one of the characteristics of an analog
signal based on the information in digital data. Digital data needs to be
carried on an analog signal. A carrier signal (frequency fc) performs the
function of transporting the digital data in an analog waveform.
Digital modulation
methods. In digital modulation, an analog carrier signal is modulated by a
discrete signal. Digital modulation methods can be considered as
digital-to-analog conversion and the corresponding demodulation or detection as
analog-to-digital conversion.
Common analog modulation
techniques are: Amplitude modulation (AM) (here the amplitude of the carrier signal
is varied in accordance with the instantaneous amplitude of the modulating
signal) Double-sideband modulation (DSB) Double-sideband modulation with
carrier (DSB-WC) (used on the AM radio broadcasting band).
Viewed from afar, the
wave function below may seem smooth and analog, but when you look closely there
are tiny discrete steps as the signal tries to approximate values: That's the
big difference between analog and digital waves. Analog waves are smooth and
continuous, digital waves are stepping, square, and discrete.
