A systematic work has been done in designing and fabricating a complete remote control guidance system, using FM-AM, for a flying vehicle. This paper deals with the selection of the proper channel following the guidance receiver on the vehicle, the necessary amplification of the command signal on that channel and the final servo stage.The channel discriminator consists of two selective amplifiers using twin-T in the feedback loops, followed by a differential amplifier. The frequency sensitive output is fed to a high current gain control amplifier with actuator coils as the loads. The complete circuit, its working, printed board layout and the results obtained are discussed.
