Hi,
I want to control a satellite dish motor based on DiSEQC1.2 protocol.
I need to merge a dc signal of 18 volt and a 22KHz pulse of about 0.6v pp. I use linear power supply as DC source and PC sound card as signal source. I have tried T-jucnction with and without an inductor series with Dc power supply and capacitance series with pulse. but it does not work, it degrades the shape of signal. would you please give me a solution?
regards
