Suppose you want to send three signals (Cos or Sin wave) through a transmission medium. Each signal is 60 degrees shifted from one another. Amplitude of the signals are 91, 36, and 69, respectively. Frequency of the signals are 369, 919, and 183, respectively.

In MATLAB, Quantize the composite signal in 8 equally distributed levels and show only 4 cycles in a new figure titled “Quantized Signal”. Use valid label in x-axis & y-axis.
