Abstract: PURPOSE:To obtain a frequency synthesizer which can be switched in frequency at a high speed. CONSTITUTION:A phase locked loop circuit 17 outputs the same frequency at all times. A digital direct oscillator 18 consists of a clock generator 11, a control part 10, a memory 9, and a D/A 8. A sine wave is outputted by outputting the momentary value of a sine wave stored in the memory 9 to the D/A 8 by using the control circuit 10. The digital direct oscillator 18 varies the frequency of the outputted sine wave by varying intervals of the head address and read addresses of the read memory according to external data.
