Abstract
PURPOSE: To prevent the unsteady sequence ralation of the logic caused by the obscure time information of the control signal and thus to eliminate the malfunction and to secure the steady control action, by controlling the reception detecting velocity of the control signal in accordance with the reception input level.
CONSTITUTION: The arrival signal caught by antenna 11 is demodulated via receiver 12, and the control signal is selected by BPF13 and then amplified through amplifier 14. The amplified control signal is rectified through rectifier 15 to be applied to adder 16. On the other hand, part of the demodulated output of receiver 12 is applied to input level detector 18 to detect the input level, and the output which detected the input level is applied to adder 16 to control the response velocity of the output of rectifier 15 which selects the control signal in response to the output of detector 18. In other examples of application, gain control signal generator 20 is provided to detector 18 output to generate the gain control signal according to the reception level detection output. With this control signal, the gain of amplifier 14 is controlled.
