In a ASK system, the amplitude of the carrier signal is 10V and the binary to be transmitted is {1, 0, 1, 1, 1, 1, 0, 0, …}. The amplitude of the output will be:

A. {± 5V, 0, ± 5V, ± 5 V, ± 5V, ± 5V, 0, 0,…}
B. {0, ± 10V, 0, 0, 0, 0, ± 10 V, ± 10 V, …}
C. {± 10 V, 0, ± 10 V, ± 10 V, ± 10 V, ± 10 V, 0, 0, …}
D. {± 1 V, 0, ± 1 V, ± 1 V, ± 1V, ± 1V, 0, 0,…}
Answer» D. {± 1 V, 0, ± 1 V, ± 1 V, ± 1V, ± 1V, 0, 0,…}
