SOME OBSERVATIONS ON THE FARADAY EFFECT

Some observations on the pedestal effect.

The pedestal or dipper effect is the large improvement in the detectability of a sinusoidal grating observed when it is added to a masking or pedestal grating of the same spatial frequency, orientation, and phase. We measured the pedestal effect in both broadband and notched noise-noise from which a 1.5-octave band centered on the signal frequency had been removed. Although the pedestal effect ...

Observations of the Faraday Instability

First observed by Michael Faraday in 1831 [1], Faraday waves are surface instabilities that arise in a fluid undergoing vertical oscillations above a critical amplitude and/or frequency. Faraday himself measured that the resulting surface wave frequency was equal to half the driving frequency. Above this critical amplitude/frequency the fluid surface can exhibit an incredible variety of pattern...

Some observations on impedance and Ferranti effect

It could be assumed that there is little or no uncertainty left at all regarding electrical resonance, 150 years after (1865) James Clerk Maxwell wrote a letter to Sir William Grove explaining the whole theory of the condenser in multiple connection with a coil, and 122 years after Arthur Edwin Kennelly presented his paper on impedance to the American Institute of Electrical Engineers. Neverthe...
