专利汇可以提供Data transferring system utilizing frame and bit timing recovery technique专利检索,专利查询,专利分析的服务。并且The transmitter-encoder of the data transferring system includes a combiner which develops an information signal by sequentially sampling the output states of a plurality of data sources. A timing signal generator develops bit and frame timing control signals for the combiner and a carrier and two pilot signals which are synchronized with the control signals to facilitate timing recovery at a receiver-decoder of the data transferring system. A composite signal comprised of an encoded information signal, carrier and pilots is transferred to the receiver through a medium which might produce abnormal information, such as an undesired frequency shift or phase perturbations, in the signal at the receiver-decoder input. The receiver includes circuitry which derives the carrier signal to facilitate demodulation. A demodulation circuit establishes the difference of each of the pilot signals and the encoded information signal from the carrier to produce two difference mixing signals and a difference information signal which have any frequency shift caused by the medium eliminated therefrom. One of the two difference mixing signals is utilized to reconstruct the bit timing signal and the other mixing signal along with a control signal derived from the bit timing signal is utilized to provide a frame timing signal which does not have any frequency or phase ambiguity. The bit and frame timing signals operate a bit separator included in the receiver which selectively channels the decoded data from the information signal to each of a plurality of data utilization devices corresponding to each of the data sources. A monitor signal which is synchronized with the data signal and which has a known pulse code may form part of the information signal to facilitate secure data transmission.,下面是Data transferring system utilizing frame and bit timing recovery technique专利的具体信息内容。
