[Discuss-gnuradio] Clarification

[ranjini ram]

hi List,

i need your immediate help.I tried doing FSK modulation using GRC.i ll give the flow graph which i did.

signal source(square)-->throttle-->FM mod-->Multiply-->cmplx to float-->scope sink
                                                      |
                                                carrier sig(cosine)

Actually am getting for logic0 one freq and logic1 another freq at the output.in practical case we will take two different carrier frequency f1 and f2 right.but here without taking two am getting the output plot.i took source freq as1KHz and carrier freq as 8KHz.


please do correct me if any mistake in my flow graph...here with i ve attached the screen shot of the flow graph.
