<p>An amplifier circuit is placed in the wheel assembly of the landing gear of an aircraft. The amplifier circuit amplifies a signal whose frequency is proportional to the speed of the wheel prior to transmitting the signal over a transmission line to sensing and control circuits. This permits a high frequency signal to be generated at the wheel assembly and insures that the signal has sufficient power to be sensed by a remotely located sensing circuit even though the signal may be attenuated by the capacitance in the transmission line. This permits a higher frequency signal to be generated than previously possible. This provides greater wheel speed resolution and enhanced sensitivity for aircraft landing gear anti-skid systems.</p> |
