Claim Text:
1. A method for pulse encoding, the method comprising: calculating an index value of an input pulse; selecting a first adjustment threshold value according to the number of pulses; comparing the index value of the pulse with the first adjustment threshold value; if the index value is smaller than the first adjustment threshold value, adopting the first number of encoding bits to encode the index value, if the index value is not smaller than the first adjustment threshold value, adopting the second number of encoding bits to encode the index value plus an offset value, wherein the first number is smaller than the second number, the first number and the second number are both positive integers, and the offset value is greater than or equal to the first adjustment threshold value; and wherein selecting a first adjustment threshold value according to the number of pulses comprises:
