1) Determine the number of possible PCM values that can be encoded for (a) 6 bits and (b) 10 bits.
2)it is desired to represent an analog signal in no less than 500 values. determine the minimum numbber of bits required for each word.
3)The constellation diagram for a particular QMA system has four different amplitudes and each amplitude has eight different possibles phase shifts. Determine the number of bits per symbol.
