Wheel Electronics and Tire Control System for Measuring a Measurand is provided. The wheel electronics may include a receiving device for picking up and digitizing an amplitude-modulated request signal, which has a carrier frequency for encoding a request, having a first evaluation device, which checks the request signal for the presence of a request contained therein, and having a digital counter for generating an envelope of the request signal, which has a counter input for coupling the request signal, which is clocked at a clock signal frequency different from the carrier frequency and is determined from the clock signal frequency and the request signal of its envelope. Furthermore, the invention relates to a tire control system for measuring a measurand with this type of wheel electronics.
