Signal separating device. |
摘要 |
<p>A heating element (2) of a heated window of a vehicle can be used as a radio aerial in two different configurations permitting diversity reception or transmission. Provision is made for switching between the two configurations so that fading in one configuration can be compensated by better receiving or transmitting characteristics in the other. The two configurations may be separated by a centre-tapped transformer (23, 24) which gives balanced and unbalanced aerial characteristics. A switching circuit (37) may be provided to switch repeatedly between the two configurations. Alternately, switching may be effected under the control of a circuit (35) which monitors signal strength. </p> |
