SINE WAVE OSCILLATOR AND INDUCTIVE SENSORS |
摘要 |
A sine wave oscillator for an inductive sensor system is disclosed. The sine wave oscillator comprises a decoupler and a low-pass filter, wherein the decoupler is configured to provide a pulse width modulated signal as a decoupled signal at one output of the decoupler. One input of the low-pass filter is connected to the output of the decoupler. The low-pass filter is configured to provide a sinusoidal signal for the inductive sensor system by using the inverted signal at an output of the low-pass filter. The sine wave oscillator further comprises a microcontroller that is designed to provide the pulse width modulated signal with a predetermined frequency and a predetermined duty cycle at one pin of the microcontroller. |

1. A sine wave oscillator for an inductive sensor system, the sine wave oscillator comprising:
a decoupler and a low-pass filter, wherein the decoupler is configured to provide a pulse width modulated signal as a decoupled signal at one output of the decoupler, wherein one input of the low-pass filter is connected to the output of the decoupler, and wherein the low-pass filter is configured to provide a sinusoidal signal for the inductive sensor system by using the decoupled signal (150) at one output of the low-pass filter, wherein a microcontroller is designed to provide the pulse width modulated signal with a predetermined frequency and a predetermined duty cycle at one pin of the microcontroller. |
