Hi
I am working on the power line communication project.
I have implemented FSK modulation and demodulation using XR2206 and XR2211 respectively.
I am getting 30khz and 15KHz, 5Vpp output for logic 1 and logic 0 respectively.
I have also implemented the coupling circuit using ferrite core from the power supply and couple it
using .47uF - 300V capacitor(capacitor conected on the high voltage side) . Now the problems comes when i integrate the ouput of the FSK
with the input of transformer. After connecting the transformer with the ouput of FSK
the voltage drops from 5Vpp to 0.1Vpp.
Please tell me any idea to solve this problem
Waitng for positive reply.
