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.
