In amplitude modulation, the message signal
Vm(t) = 10 sin (2\(\pi\) \(\times\) 105t) volts and
Carrier signal
VC(t) = 20 sin(2\(\pi\) \(\times\) 107 t) volts
The modulated signal now contains the message signal with lower side band and upper side band frequency, therefore the bandwidth of modulated signal is \(\alpha\) kHz. The value of \(\alpha\) is :
