Amplitude Modulation and how it is expressed

In communication a carrier signal is a sinusoidal signal denoted by C(t)=Ac Cos(2ᴨfct) Ac= Amplitude of the carrier C(t)= carrier signal fc= carrier frequency This carrier signal is fundamental in any communication system message signal or baseband signal is modulated. There are many ways to modulate the signal one amongRead More →

benefits of modulation and its techniques

Modulation allows you to transmit information using radio signals and benefits of modulation includes height of the antenna is reduced, it reduces the interference among the signals, mixing of signals is reduced, multiplexing of signals is possible, long distance communication is possible. Benefits of Modulation 1 .Height of the AntennaRead More →
