专利汇可以提供Electronic repeater servo专利检索,专利查询,专利分析的服务。并且An electronic servo system utilizing a voltage controlled oscillator to drive a plurality of associated flip-flops to develop phase-variable, quadrature square wave output signals. These quadrature output signals are then used in a feedback loop, in conjunction with electrical signals corresponding to the sine and cosine functions of a shaft angle of a remote synchro transmitter, to drive demodulators whose outputs are summed in an amplifier to produce an error signal which controls the oscillator signal. The system operates to null the error signal and phase-lock the oscillator signal such that the electrical phases of the quadrature output signals are accurately positioned to be proportional to the shaft angle of the remote synchro transmitter. The respective quadrature output signals of, for example, two of the electronic servo systems may be utilized in conjunction with signals to be resolved to drive demodulators whose outputs are respectively summed in one channel and remodulated, demodulated and selectively summed in another channel to compute the vector rotations necessary for electronic resolution.,下面是Electronic repeater servo专利的具体信息内容。
