Abstract This paper introduces a new method with which the DC signal can be directly converted to AC signal by using a 32 pathways switch chip.Because the response time of the switch chip is very short, oscillator frequency can reach more than 100 kHz. The experiment show that the oscillating circuit sine signal has characteristics of the stability of signal cycle, higher repeatability and is suitable for the oscillation source as a geological instrument.
Key words :
