Hi i Work with FXTH871511DT1
I try to understand LF receiver but i have two questions.
1- I can transmitt data with PWM to 125Khz coded to manchester and FXTH87 i can see the data that i sent, or i need a carrier signal to envelop the data to trasmitt.
2- If i need to carrier to transmitt the data How i can do it? I can generate 125Khz frequency and RC filter to 125Khz base-band and antenna or i need something else to modulate the data.
