Question

Which of the four digital-to-analog conversion techniques is the most susceptible to noise? EXPLAIN WHY.

a. ASK
b. FSK
c. PSK
d. QAM

Answer 1

a. ASK.

Step-by-step explanation:

ASK(Amplitude Shift Keying) :- It is the form of amplitude modulation.It represents digital data variations in the carrier wave's amplitude.

It is most susceptible technique to noise because among the frequency or phase and amplitude ,amplitude is most affected by the noise as compared to frequency.
