In the case of -ary unipolar NRZ with M=4 and maximum value of voltage V=1 Volts, calculate the energy per symbol in the case the symbol Rate . In this case assume the following Probabilities for the symbols:

• Pr(00) = 0.4
• Pr(01) = 0.1
• Pr(11) = 0.1
• Pr(10) = 0.4

The symbols are encoded using the gray coding as follows:

• 00 is associate with 0 volts;
• 01 is associated with Volts;
• 11 is associated with Volts;
• 10 is associated with Volts;
