Light and repetitive visual signals can induce epileptic seizures (see Bucha effect).
For measuring repetitive signals, this type can have bandwidth and high-speed timing up to ten times higher than any other oscilloscope.
This method can only work for repetitive signals, not transient events.
Human listeners are able to decode the repetitive variable signal of running speech and to translate it into phonemic components.
It was not an oscillator in the electronic sense that it generated a repetitive signal, in fact electronic oscillators did not yet exist when this device was created.
Digital pattern generator can produce either repetitive, or single-shot signals in which case some kind of triggering source is required (internal or external).
Frequency counters usually measure the number of oscillations or pulses per second in a repetitive electronic signal.
It is the case that any repetitive signal can be reduced down to a Fourier series of sine waves.
It answers the facts better than the theory of a natural cause for a complex repetitive signal coming to us in several media.
