Teori

Bakgrunn

As mentioned in section 2.7 there is electromagnetic noise present when the tesla coil is used and a robust channel is needed for signal X2 because this signal is transmitted from the pulse shaper to the tesla coil driver, wich as mentioned in section 2.1 are physically located in different chassis some distance apart. For this plastic optical fibre is chosen. To further increase the robustness the signal X2 is modulated. The robustness and possible noise introduced in this channel is not discussed further as it can be treated as an isolated problem and is assumed well understood and documented in the field of electronics. A diagram of the optical channel is shown in fig. 2.13. Where CW is the carrier wave used to modulate the signal X2, PWM is the modulated signal X2. The blocks tx and rx are the optical transmitter and reciever.
