Abstract
PURPOSE: To increase the memry accuracy for the preset frequency by counting and memorizing the local oscillation frequency and then giving a comparison and decision between the memory signal and the counter output with a control to secure an indentification between them at all times.
CONSTITUTION: Counter 30 counts the frequency of local oscillator 13 and then memorizes the output signal in emory unit 411. A comparison is given between the memory signal and the output signal of counter 30 under the receiving state along with a decision. When some difference is detected between the both signals, frequency decision control circuit 42 of reception frequency control unit 40 has a control to secure an identification between the comparison signal and the variable signal of frequency variable code generator 23. As a result, the memory accuracy can be increased for the preset frequency.
