PEMF Devices
Spark Chamber Vs Digital Devices
Analog or Spark Chamber devices typically produce PEMF signals through the discharge of energy via a spark chamber, which might result in a slightly different electromagnetic waveform compared to digital machines, which use electronic switches. These differences can influence the sensation experienced by the user.
Analog or Spark Chamber Devices
In Analog Devices, the spark chamber is used to generate the PEMF signal. When the capacitor reaches a certain energy level, it discharges through the spark chamber, creating a spark. This spark generates a waveform known as a "spike" or "impulse." This waveform has a sudden, sharp increase in electromagnetic energy followed by a quick decrease, resembling a spike, which is then directed to the body through a coil. The distance between the electrodes in the spark chamber can influence the strength of the spark and, consequently, the intensity of the PEMF signal.
Digital Devices
Digital PEMF devices, on the other hand, produce square or modified square waveforms. These waveforms consist of abrupt shifts between two levels: high intensity representing the pulse's peak and low intensity representing the baseline. Square waveforms have consistent duration and intensity, with sharp changes. These waveforms are electronically generated by the machine's controller and switches, allowing precise adjustment of intensity, frequency, and duration of pulses.
