Method and device for processing a received signal transmitting coded data
First Claim
1. Method of conditioning a received signal that contains amplitude-coded data, wherein the coding of the individual data includes a defined coding clock pulse, and wherein the received signal includes edges produced in accordance with the coding clock pulse, and wherein the received signal includes the signal of an active sensor of a vehicle wheel, comprising the following steps:
- determining, from the received signal, a time constant (tm) set in accordance with the coding clock pulse, wherein said time constant is determined in accordance with the duration of a first pulse, and conditioning portions of said received signal according to the first pulse, at fixed times in accordance with the time constant (tm), determining a first and a second time in accordance with the time constant (tm), wherein the second time is set in dependence on the time of an edge determined at the first time, conditioning a first signal part which has a first edge at the first time, conditioning a second signal part at the second time, and detecting another edge in the received signal at a third time set in accordance with the time constant (tm), wherein the third time is set based on an edge which has been detected as a last edge.

Abstract
The present invention relates to a method for conditioning a received signal that transmits coded data, wherein the coding of the data includes a defined coding clock pulse and the signal includes edges produced in accordance with the coding clock pulse, wherein from the received signal a time constant (tm) set in accordance with the coding clock pulse is determined, a first signal part which has a first edge is conditioned at a first time that is set in accordance with the time constant (tm) or in a first time window that is set in accordance with the time constant (tm), and a second signal part which has a second edge is conditioned at a second time that is set in accordance with the time constant (tm) and in dependence on the time of the first edge or in a second time window that is set in accordance with the time constant (tm) and in dependence on the time of the first edge.
