When these spurious signals have a power level that is higher than the thermal noise floor, then the receiver is desensitized.
When an interfering signal is present, it can contribute to the level of the spurious signals.
The effects of atmospheric variations and spurious signals can be reduced via signal processing means.
Its video processor system, it seems, was emitting spurious signals on the 121.5 frequency.
Intermodulation in the system causes spurious signals (distortion) at to appear.
That means their sensors have a lot of spurious signal to put up with when they're shielded.
They waited another two minutes to make sure it wasn't a spurious signal.
They were designed to ignore spurious signals from lightning, sunlight, or electrical surges.
The problem showed up as spurious signals from a fuel-pump sensor.
In a transmitter, these spurious signals are generated along with the one desired signal.
