A signal of frequency (10 kHz ) and peak voltage (10 ~V ) is used to amplitude modulate a carrier of frequency (1 MHz ) and peak voltage (20 ~V ). The side-band frequencies in ( kHz ) are

Step-by-step solution

Given, frequency of signal, (f_s=10 kHz ) peak voltage, (V_p=10 ~V ) carrier frequency, (f_c=1 mHz ) and peak voltage, (V_c=20 ~V ) ( ) The side band frequencies are given as (f=f_c f_s ) Putting the given values, we get (f=1 10^6 10 10^3 ~Hz =(1000 10) 10^3 ~Hz ) So, the side band frequencies in ( kHz ) is (1010 kHz ) and (990 kHz ).
