(a) Consider the double sided magnitude spectrum of the message signal W illustrated in Figure Q2.1. W(f) (1) (ii) (iii) W(0) - 8 kHz 8 kHz Figure Q2.1: Double sided magnitude spectrum W(f). Calculate the total number of radio stations that can be simultaneously accommodated in a bandwidth of 40 kHz for the following modulation schemes: Double sideband large carrier (DSB-LC). [2 marks] Double sideband suppressed carrier (DSB-SC). [2 marks] Single sideband (SSB). [2 marks] (a) Consider the double sided magnitude spectrum of the message signal W illustrated in Figure Q2.1.
