### Electrosmog

 Electrosmog is a popular term indicating that an electric device generates disturbing electric and/or electromagnetic radiation, which are either transmitted into the air, like your cell phone, or fed back into the mains power grid.  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. Electrical frequencies not only contain the specific desired generated vibration frequency, but also cause so called 'harmonic' frequencies. A harmonic of a wave is another frequency wave, which is a multiple of the original generated frequency. For example, if the generated pulsing frequency is 10 Hz, the first harmonic is 20 Hz, the second harmonic is 30 Hz, the third harmonic is 40 Hz etc. Although these unwanted harmonic signals decrease in strength very fast for each next step, they are still undesirable signals and it is important 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) you should be able to see that the moment the pendulum reaches its highest point at either side, it stands still for a very short moment, just before it returns to the other side, where it again stands still for a very short moment at its highest point.  The path of the pendulum is actually a perfect sine wave!  Any PEMF 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 switching is synchronized 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! Many different forms of power line disturbances (noise) exist. Here is just one example of noise caused by by EMI (Electro Magnetic Interference) or RFI (Radio Frequency Interference). The picture shows electrical noise superimposed on a regular power line sine waveform.  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.
