3.16 Example 16: Generate a DSB-AM Modulation
Waveform
Generate a DSB-AM modulation waveform with 100Hz modulating frequency.
The carrier is a sine wave with 2kHz frequency.

Steps:

Set the frequency, amplitude and offset of the carrier wave.
1. Press Waveforms, and choose the sine waveform as the carrier wave.
2. Press Frequency/Period and choose Frequency which will display in blue
color. Input ‗2‘ from the keyboard and choose the unit ‗kHz‘ to set the
frequency to 2kHz
3. Press Amplitude/HighLevel and choose Amplitude which will display in
blue
color. Input ‗4‘ from the keyboard and choose the unit ‗Vpp‘ to set the
amplitude to 4Vpp.
4. Press Offset/LowLevel and choose Offset which will display in blue color.
Input ‗0‘ from the keyboard and choose the unit ‗Vdc‘ to set the offset to
0Vdc.

Set the modulation type DSB-AM and parameters.
1. Press Mod
→ Type → DSB-AM, choose DSB-AM. Please notice that the
message shown on the middle left side of the screen is ‗DSB-AM ‘.
2. Press DSB Freq
, input ‗100‘ from the keyboard and choose the unit ‗Hz‘ to
set the DSB Freq to 100Hz.
When all parameters above are set, the waveform generated is shown in
Figure 3-16.
