[Discuss-gnuradio] Help with GRC

[ajmerasomya]

Hi, I am trying to transmit a sine wave modulated with different modulation schemes using GRC. What I don't understand is that at the receiver, since the output of the demodulator is in bits(0,1), what block should I connect in order to see my reconstructed sine wave?  I connected a scope sink at the output of the demodulator where I was able to see a waveform between 0 and 1, but I actually need to see the original sine wave.

Also about the type conversions, do these conversions are specifically because of the data types in C++. What I understand from them is that some blocks may take input in bytes and their output may be complex , so in order to connect them to another block with different input output types, we need these type conversions. Also the block input-output data type is dependent upon the type of data they are meant to process. Is my understanding correct?

Any help is really appreciated.

Thanks & Regards,
