‫Now, in the case of amplitude modulation, which is an analog modulation scheme.
‫If this is the message signal and this is the carrier, then we can easily generate the amplitude modulated
‫signal by simply multiplying the message signal with the carrier.
‫So if we have the message MFT and we multiply it, it does get here cause of megacity.
‫We'll get the modulated signal.
‫Now this original message signal mft if we take the 40 or transform of this original message signal,
‫we will see that it is centered at these zero hertz frequency.
‫And it has the bandwidth of B.
‫But once this message signal is modulated and if we take the 40 or transform of the modulated, this
‫modulated.
‫Signal, then we would see that this original message signal is now shifted to the carrier frequency,
‫and we would also see that the bandwidth of the message signal in the modulated form is no double as
‫compared to the original baseband signal.
‫And here we are measuring the bandwidth from the point where the message signal is zero to the point
‫where the message signal again becomes zero.
