Abstract
Methods and systems for simply and inexpensive converting the signals of solid-state sensors for use by analog systems and indicators. An embodiment of the system receives a DC voltage value from at least one sensor, converts the DC voltage value into one or more analog signals based on a reference AC voltage signal, and performs at least one of outputting or storing the generated analog signals. The conversion is performed digitally then converted to analog or is performed using an analog trigonometric converter.
Claims9
A system comprising:
- at least one sensor configured to output a sensor value in the form of a DC voltage value;
- a trigonometric converter for converting the outputted DC voltage value into one or more analog signals based on a reference AC voltage signal;
- and
- a component configured to perform at least one of outputting or storing the generated one or more analog signals,
- wherein the trigonometric converter comprises:
- an analog to digital converter configured to convert the DC voltage value into a digital value;
- a non-linear transfer function component configured to convert the digital value into a digital trigonometric value using a non-linear transfer function;
- a digital offset component configured to add an offset value to the digital trigonometric value;
- a first multiplier configured to multiply the reference AC voltage signal to the digital trigonometric value;
- and
- a second digital analog multiplier configured to multiply the reference AC voltage signal to the output of the digital offset component.
