AM and DSBSC waveform comparison ?

AI Thread Summary
AM modulated waveforms with a carrier and DSBSC waveforms exhibit distinct visual differences on an oscilloscope. In AM, the carrier is present, resulting in a waveform that varies in amplitude according to the modulating signal, while DSBSC lacks the carrier, leading to a waveform that peaks only when the modulating signal peaks. The DSBSC waveform shows no amplitude variation during the modulating signal's dips, making it appear more compressed. This difference is crucial for understanding modulation techniques in communication systems. Visual analysis of these waveforms can enhance comprehension of their respective properties and applications.

Hello, I am wondering what sort of visual differences you would see between an AM modulated waveform with carrier and a DSBSC waveform (suppressed carrier) in the time domain on an oscilloscope.

Any help would be appreciated.

Hi fran1942! In DSBSC the RF signal peaks when the modulating signal both peaks and dips. www.egr.uh.edu/courses/ece/ece4371/ece4117_files/A1_manual_pp33_46.pdf
