COMMUNICATIONS DEVICE WITH ADJUSTMENT FOR TEMPERATURE DEPENDENT SIGNAL DELAYS

摘要

A communications device in which a control unit and a delay unit transmit a time-shifted acknowledge signal in response to a received message. For the purpose of adhering exactly to the difference in time between receiving the request signal and sending the acknowledge signal, the control unit is connected to a temperature sensor and an adjustment-value memory. By means of the temperature sensor the control unit takes an adjustment value from the appropriate memory address and passes this adjustment value to the delay unit for determining the delay time. A field of application is, for example, mobile radio receivers for car telephone systems.
