As shown in Figure 8; This routine workflow is at first carried out system initialization after beginning; Wait for the input of keyboard special module; After keyboard special module input target frequency value or the command information; Calculate and Logic control module receiving target frequency values or command information; And then resolve target frequency value or the command information that is received, said target frequency value or command information are discerned; Calculating and Logic control module are judged the information of input, after the information that inquires input is numeral or decimal point, then judge whether to press selection key, otherwise carry out reset operation or return the input of wait keyboard special module.
After the information that inquires input is numeral or decimal point; Whether inquiry is then pressed is selection key; Until what press is then buffer memory target frequency value of selection key; Generated frequency data or command information data, and said frequency data or command information data are sent to the frequency synthesis subelement of state for " spare time ".
After the frequency synthesis subelement successfully receives said frequency data or command information data; Feedback " hurrying " state is to calculating and Logic control module; After successful synthetic and export target frequency; The feedback states " spare time " that sends the frequency synthesis subelement finishes the synthetic of this target frequency to calculating and Logic control module.
Can adopt reset key or function button to carry out the initialization operation of system and the initialization operation of frequency synthesis subelement in the workflow of the present invention; After the initialization operation; Corresponding frequency synthesis subunit state is " spare time "; Return and wait for that the keyboard special module is from primary input target frequency value or command information; Export channelized frequencies simultaneously, realize the channelized frequencies generating means.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
