As we have learned

Modulation -

It is the process carried out at transmitter in which the low frequency message signal is superimposed on a high frequency carrier signal.

- wherein

 

 The objective of modulation is to make transmission feasible and noise free . If modulation with a carrier wave of high frequency is not done , transmission would not be possible to long distant location .It is obvious that modulation shall occur before the transmission ,Thus transmission channel and receiver can not be the answer .

NOw we know that transmitter is a device which enables the modulation of  message signal with high frequency carrier wave
