Abstract
A method of driving a counter system with zero accumulated error includes setting a counter frequency of a counter transmitter, setting an original time count string according to the counter frequency, setting a first time count string of the counter greater than the original time count string, setting a second time count string of the counter smaller than the original time count string, and accumulating at least one first time count string and at least one second time count string over N cycles for generating a transmitter time count string. N is greater than two. A real time string generated by the original time count string over the N cycles is equal to the transmitter time count string.

A method of driving a counter system with zero accumulated error comprising:
- setting a counter frequency of a counter transmitter;
- setting an original time count string according to the counter frequency;
- setting a first time count string of the counter greater than the original time count string;
- setting a second time count string of the counter smaller than the original time count string;
- and
- accumulating at least one first time count string and at least one second time count string over N cycles for generating a transmitter time count string;
- wherein N is greater than two, a real time string generated by the original time count string over the N cycles is equal to the transmitter time count string.
A counter system with zero accumulated error comprising:
- a counter transmitter comprising:
- a counter module;
- a bit truncating module coupled to the counter module;
- and
- a digital encoder coupled to the bit truncating module;
- and
- a counter receiver comprising:
- a digital decoder coupled to the digital encoder of the counter transmitter;
- and
- a bit compensation module coupled to the digital decoder;
- wherein the counter transmitter sets a counter frequency, the counter transmitter sets an original time count string according to the counter frequency, the counter transmitter sets a first time count string of the counter greater than the original time count string, the counter transmitter sets a second time count string of the counter smaller than the original time count string, the counter module accumulates at least one first time count string and at least one second time count string over N cycles for generating a transmitter time count string, Nis greater than two, a real time string generated by the original time count string over the N cycles is equal to the transmitter time count string.
