Answer is:
yes
Explanation:
In Amplitude modulation if one of the two side bands is removed by a filter it is possible to recover the modulating signal
Answer is:
0.662
Explanation:
m= M/A A is the carrier amplitude. Where, M is the modulation amplitude and is the peak change in the RF amplitude from its unmodulated value.
Answer is:
985 kHz, 975 kHz
Explanation:
A standard AM broadcast station is allowed to transmit modulating frequencies up to 5 kHz. If the AM station is transmitting on a frequency of 980 kHz, maximum and minimum upper and lower sidebands are 985 kHz, 975 kHz
Answer is:
10 kHz
Explanation:
Pt = Pc( 1 + m2/2)
