PCM Encoding-Converting Quantized decimal sample values in to binary

Converting Quantized decimal sample values in to binary.

  //Encoding: Converting Quantized decimal sample values in to binary
   //x = input sequence
   //L = number of qunatization levels 
   //en_code = normalized input sequence
