| Abstract: | The essay deals with using a MC1648P chip produced by morotola company and varactors, inductances to form a circuit to realize a certain frequency range of high frequency signal. We get a velocity-controlled LC oscillator using the devides introduced above. It also explores using a SCM system formed by 89C51 SCM and TLC5615CP D/A convert chip to realize the velocity control of the varactors, to display the live concussion frequency and the peak-to-peak value. |
