Radiated electrical signals may cause humming and noise in other devices, like on a radio. Electric disturbance signals fed back into the electric grid simply turn up at other mains outlets and cause similar noise problems as radiated electrosmog.
Like all electrical devices, PEMF therapy devices may also radiate and/or send back electrical disturbance signals into the power grid, if they are erratically designed. It is important to understand exactly the causes of these undesired signals in order to be able to suppress them at source.
In addition, electromagnetic pulsing fields outside the set therapy frequency are uncalled for, being another reason why suppression is an absolute must in PEMF devices.
When pulsing wave signals are non-sinusoidal it becomes impossible to avoid or suppress these unwanted harmonic frequencies, which is another reason why sine wave signals need to be used exclusively in pulsed electromagnetic field therapy devices.
But even in the latter case, due to the very fast 'on' and 'off' switching of the wave signal, it is crucial to switch them 'on' and 'off' exactly the moment the sine waves cross their zero point.
For example, when you look at a pendulum clock (invented by another Dutch guy, the scientist Christiaan Huygens)
The path of the pendulum is actually a perfect sine wave!
Any PEMFT device pulsing with any other wave form other than a pure sine wave causes electrosmog, but even if pure sine waves are the basis of the pulsed signal, it is crucial that the individual pulse 'on' and 'off' switching occurs exactly the moment the sine wave crosses its zero point, being the very short moment the pendulum is at complete standstill.
It is only by perfect synchronization between the electronics hardware and software, as developed for the Curatron devices, that this very difficult task can be achieved!
These random electrical noise signals travel through the power grid and can easily cause undesirable effects in computers and electrical appliances connected to the same power grid.
Inside the PEMF Curatron device, a special filtering system prevents electrical disturbance signals from being fed into the power grid while at the same time blocking existing electrosmog signals coming out of the power grid.
