Which of the following four alternatives is not correct? We need modulation WIEEE 2011] (a) to increase the selectivity (b) to reduce the time lag between transmission and reception of the information signal (c) to reduce the size of antenna (d) to reduce the fractional bandwidth, that is the ratio of the signal bandwidth to the centre frequency

Round 2
The purpose of oscillation in the AM signal (a) provide modulating signal (b) provide carrier (c) provide enough power to meet transmission system requirement (d) none of the above
In AM, the centpercent modulation is achieved when (a) Carrier amplitude = signal amplitude (b) Carrier amplitude not equal to signal amplitude (c) Carrier frequency = signal frequency (d) Carrier frequency not equal to signal frequency
