Use the TIMS “Variable DC” module to generate a 1V DC signal.
Use the “Adder” module to add this DC signal to the message
signal generated in task 1 (this will produce the
[1 + K_a m(t)] part
of the AM signal).
Use a “Multiplier” module to multiply this with the carrier signal
c(t) generated in task 2.
You will now obtain the full DSB AM signal:
Display the time-domain of this signal as well as its spectrum on LabVIEW.
Question - Compare the envelope of this signal with the original message signal, m(t) (You can display both the original signal and the AM signal on the oscilloscope to accurately compare them), how do they relate to each other?
Following picture are the result for this exercise but I am not exactly sure how to answer the question above "how do they relate to each other". Could you please explain me or give me any hint to start.
Thank you! Appreciate it!
