WebSpurious emissions are emissions which are caused by unwanted transmitter effects such as harmonics emission, parasitic emission, intermodulation products,3 and frequency conversion products, but exclude OOB emissions. WebMoreover, we are getting one prominent spurious at the output which changes with output frequency. I am attaching images of DAC output for one channel at 192MHz output and othe rat 153.6MHz output. Since the spurious changes with frequency as seen in the pictures, when we sweep the output using NCO, we can see our main output sweeping with the ...

In radio communication, a spurious emission is any component of a radiated radio frequency signal the complete suppression of which would not impair the integrity of the modulation type or the information being transmitted. A radiated signal outside of a transmitter's assigned channel is an example of a spurious emission. Spurious emissions can include harmonic emissions, intermodulation products and frequency conversion products. Web6 Jun 2024 · RF transmitters are an essential part of modern communications.
