1 transmitter with 2 input

hello
i want to ask can i use 1 transmitter with 2 input then connect with 1 receiver..
in this project i use RF module 433 Mhz..

You do not say what your two inputs are. In general using analogue inputs require that the two signals are seperated in frequency, so they can be filtered off and then separated. A typical example is the stereo FM transmision. The base band signal is the mono signal ( R+L). There is another carrier added with a centre frequency of 38 KHZ, which carries the stereo difference signal ( R-L). In the receiver the 38 KHZ is filtered off and demodulated, giving the R-L signal. this is added to a bit of the R+L, will give a 2R output. The R-L signal is also subtracted from the R+L to give 2L. So the left and right hand channels are recovered.
