Question

Base on the above encoding table and diagram, please answer what type of encoding is this whether its FM, AM, or PM or combinations of these?

MODULATION B ENCODING TABLE: Symbol Phase Amplitude Symbol Phase Amplitude Symbol Phase Amplitude Symbol Phase Amplitude 45.00° 1.41 45.00° 2.83 63.430 2.24 26.57 2.24 0100 0101 0110153.43° 2.24 0111 1000 225.00° 1.41 1001 1010 243.43° 2.24 1011 315.00 1.41 315.00° 2.83 1110 333.43° 2.24 296.57° 2.24 135.00° 1.41 1100 0001 0010 0011 135.00° 2.83 225.00° 2.83 1101 116.57 2.24 206.57° 2.24 MODULATED SIGNAL:

Explanation / Answer

Answer is as follows :

The Given type of modulation is PM i.e. Phase Modulation.

Because there are variations in the instataneous phase of carrier signal.

So we see that in the encoding modulated Signal there are variations in wave diagram.

But we know that phase modulation is closely related to frequency modulation that leads to create quadrature amplitude modulation.

so we can say that the given type of encoding is combination of Phase Modulation and Frequency Modulation.
