Assuming you mean analog AM transmitter, you use a float-to-complex,
connect a constant source with value of 1 to IM input.
Then the audio source connects to RE input.
You will need an adjustable attenuator on the complex output before going
to the sink device.
Using a multiply const with slider,
First of all, I'm sorry that I could not understand clearly what you want.
Are you using any hardware or you are just running a simulation using *GNU
Radio*? What do you mean by waveform of transmitter? How do you integrate
AM transmitter with FM receiver?
If you have USRP and want DSBSC AM, it is
