Pronunciation varies by accent · noun
The phenomenon by which a globally band-limited signal can contain local segments that oscillate faster than its fastest Fourier components..
We conclude that, either superoscillations really can beat the bandlimit and achieve superresolution (`kinematic superresolution') or the superoscillating high frequency is absorbed and we gain dynamical access to the physics of high frequency processes with low frequency signals (`dynamical superresolution')..
Use superoscillation when its meaning, tone and grammar fit the full sentence. A synonym is not always a direct replacement.
Superoscillation means The phenomenon by which a globally band-limited signal can contain local segments that oscillate faster than its fastest Fourier components..
The closest synonym depends on the sentence and intended sense.
The opposite depends on the specific sense.
We conclude that, either superoscillations really can beat the bandlimit and achieve superresolution (`kinematic superresolution') or the superoscillating high frequency is absorbed and we gain dynamical access to the physics of high frequency processes with low frequency signals (`dynamical superresolution')..
