Solution

The correct option is C Phase

Phase modulation technique provides the fastest transmission speed.

Phase modulation (PM) is a modulation pattern for conditioning communication signals for transmission. It encodes a message signal as variations in the instantaneous phase of a carrier wave. ... The phase of a carrier signal is modulated to follow the changing signal level (amplitude) of the message signal.

Some of the most common complex techniques used in high speed DSSS WLANs include M-ary orthogonal keying (MOK), complementary code keying (CCK), cyclic-code shift keying (CCSK), pulse-position modulation (PPM), quadrature amplitude modulation (QAM), orthogonal code division multiplexing (OCDM), and orthogonal frequency .

Modulation techniques are methods that are used to encode digital information in an analog world. The 3 basic modulation techniques are as follows: AM (amplitude modulation) FM (frequency modulation) PM (phase modulation)

All analog television systems use vestigial sideband modulation, a form of amplitude modulationin which one sideband is partially removed. This reduces the bandwidth of the transmitted signal, enabling narrower channels to be used.
