I The constellation diagrams for an 8-QAM' modulator is shown in the figure below: Q 110 5 011 001 101. 111 100 010 000 1- Write down the in-phase and quadrature carrier of each data unit symbol in a mathematical form of sine and cosine i.e. Sooo(t) = Aooosin(fet) + Aooosin(fet + 0) 2- Sketch the modulated waveform produced by the 8-QAM scheme shown above for the data stream 000 111 001 101 110 100 011 010. Also, show on the sketch the pulse shape of the in-phase and quadrature data symbol and their modulations. Consider the first two bits of each data symbol as the in-phase and third bit as the quadrature. Use carrier signal with frequency f. = 2 Hz
