In Amplitude Shift Keying (ASK), how is logic 1 typically represented in Binary ASK?

Correct option is D

​$$\text{In Binary Amplitude Shift Keying (ASK):} \\[6pt]\bullet \ \text{The carrier frequency and phase remain constant.} \\[4pt]\bullet \ \text{Binary data is represented by changing the amplitude of the carrier.} \\[8pt]\text{Typically:} \\[6pt]\bullet \ \text{Logic 1 } \rightarrow \text{ carrier transmitted with a non-zero (higher) amplitude} \\[4pt]\bullet \ \text{Logic 0 } \rightarrow \text{ carrier amplitude is zero or much lower (On-Off Keying)}$$​​
