Abstract: PURPOSE: To obtain the modulation output of continuous phase and small distorsion by generating two types of frequencies through the counting of the same clock pulse.  
     CONSTITUTION: The clock pulse CL is counted by the pulse counters CTR 0 , CTR 1  to generate the frequencies Nf 0 , Nf 1  as many as n times of the modulation output frequencies f 0 , f 1 . The selector SEL selects either of the outputs of the pulse counters CTR 0 , or CTR 1  in accordance with the mark, space signals of the input signal S. The pulse counter CTR 2  receives the output of the selector SEL and divides it into 1/N thereby to generate the modulation output of 50% of duty at the frequencies f 0 , f 1 . This output is led to a lower zone wave filter and the pulse wave is converted into sine wave and thereafter it is put out as output from the output terminal into FS modulation wave.
