In the previous study, the characteristics of elements required to construct Warren's counter have been made clear. However, the elements having these characteristics had to be chosen by an experimental trial and error. Therefore, these results have not yet been sufficient to design Warren's counter.
In this advanced study, from the viewpoint of predicting the geometries of control flip-flop (FF_c) fitted to a given memory flip-flop (FF_m), the method of analizing the characteristics of FF_c is proposed.
The obtained results can be summarized as follows:
1) If the static and dynamic input characteristics of a given FF_m are given, by the proposed analytical method, it is possible to give theoretically the geometry of FF_c to be incorporated in a counter having the given FF_m. It is also possible to predict theoretically the magnitude and pulse width of an input signal countable by this counter.
2) Using this method for a given FF_m, Warren's counter can be designed without an experimental trial and error.
