i)Modulation process takes place in the modulator with two injection signals namely data orinformation and carrier. It is a vital step in generating a decent signal for electronic communication.Whenever the carrier is modulated by the information signal, new signals at different frequenciesare generated as part of the process. These new frequencies occur in the frequency spectrum withinthe range of the carrier frequency. Conclude these frequencies and mathematically explain itsgeneration with the help of diagrams.
