hi all,

i am trying to design a coupling circuit for power line communication using fsk
technique.i am thinking to design the ciruit for 110khz and 120 khz, but dont know
how to calculate the no. of turns for primary and secondary of the transformer.
i have got ferrite core of toroidal structure.also give any idea about the method of connecting the designed transformer to the mains.if any body have any figures illustrating the circuit design or any information about the design equation they are very welcome to reply.

thanks in advance
