The expression in the time domain is
Keywords：Labview
Reference address：Labview implements single sideband signal modulation (SSB) [phase shift method]
The modulator model is
In this experiment, more phase shifts are required because a total of four signal simulators are used, one is a modulation signal without shift, one is a modulation signal with shift, one is a carrier signal without shift, and one is a carrier signal with shift. Then the corresponding operations are performed according to the modulator model. The
final output is the time domain image of the carrier signal, the frequency domain image of the lower sideband of the single sideband modulation of the result signal, and the frequency domain image of the upper sideband of the single sideband modulation of the result signal.
Achieve results
The carrier frequency is 280, and the original sinusoidal signal with 280 as the center is two double peaks, which are obtained by phase shifting method.
