Abstract
A method for processing an electrical signal that is generated continuously over time and based on measurement values from a sensor and is transmitted via a line that is subject to disturbance variables, having the following features: establishing a scanning rate interval, establishing quantization levels, assigning the electrical signal to a quantization level, determining the number of changes in the quantization level in the scanning rate interval, rejecting all even-numbered changes in the quantization level within the scanning rate interval. A control device for a camshaft adjuster or for an internal combustion engine, which carries out a method of this kind.
Claims18
A method for processing an electrical signal (S) that is generated continuously over time and based on measurement values from a sensor and is transmitted via a line that is subject to disturbance variables, the method comprising:
- a) establishing a scanning rate interval (T),
- b) establishing quantization levels (Q1, Q2),
- c) assigning the electrical signal to a quantization level (Q1, Q2),
- d) determining a number of changes in the quantization level (Q1, Q2) in the scanning rate interval (T),
- e) rejecting all even-numbered changes in the quantization level (Q1, Q2) within the scanning rate interval (T).
A control device, for a camshaft adjuster or for an internal combustion engine, for processing an electrical signal (S) that is generated continuously over time and based on measurement values from a sensor and is transmitted via a line that is subject to disturbance variables, the control device configured to:
- a) establish a scanning rate interval (T),
- b) establish quantization levels (Q1, Q2),
- c) assign the electrical signal to a quantization level (Q1, Q2),
- d) determine a number of changes in the quantization level (Q1, Q2) in the scanning rate interval (T),
- e) reject all even-numbered changes in the quantization level (Q1, Q2) within the scanning rate interval (T).
