An information signal of frequency 10 kHz is modulated with a carrier waive of frequency 3.61 MHz. The upper side and lower side frequencies are:

Step-by-step solution

For frequency modulated signal, aligned & f_s=10 kHz , f _ c =3.61 MHz =3610 kHz & f _ u = f _ c + f _ s =3610+10=3620 kHz & f ₁= f _ c - f _ s =3610-10=3600 KHz aligned
