摘要:
In a synchronous detection circuit, an interpolation circuit regulates an interpolation calculation coefficient based on phase shift information when carrying out interpolation calculation processing over a digitally converted received signal. A sampling circuit samples interpolation data using a recovered clock as a reference and two clocks having phases which are advanced and delayed with respect to the recovered clock. A phase shift detecting circuit monitors a phase shift using three sampling data output from the sampling circuit and outputting phase shift information to the interpolation circuit when detecting a predetermined phase shift. A demodulating circuit performs demodulation processing using the data subjected to the sampling with the recovered clock output from the sampling circuit. Where a synchronous shift is detected, the interpolation circuit performs regulation to match a timing having a maximum signal-to-noise ratio and the recovered clock based on the amount of the phase shift.

A synchronous detection circuit includes: an interpolation circuit for regulating an interpolation calculation coefficient based on phase shift information when carrying out an interpolation calculation processing over a received signal which is digitally converted; a secondary sampling circuit for sampling interpolation data output from the interpolation circuit by using a recovered clock to be a reference and two clocks having phases corresponding to one processing clock which are advanced and delayed for the recovered clock; a phase shift detecting circuit for monitoring a shift of a phase by using three sampling data output from the secondary sampling circuit and outputting phase shift information to the interpolation circuit when detecting a predetermined phase shift; and a demodulating circuit for carrying out a demodulation processing by using the data subjected to the sampling with the recovered clock output from the secondary sampling circuit. In the case in which a synchronous shift is detected, consequently, the interpolation circuit carries out a regulation in such a manner that a timing having a maximum SN ratio and that of the recovered clock are matched with each other based on the amount of the phase shift obtained from the phase shift detecting circuit. Therefore, it is possible to implement a synchronous follow-up with high precision.

A method of recording and reproducing audio signals and corresponding visual signals in parallel tracks extending in the longitudinal direction on a magnetic tape, includes the steps of recording the audio signals in first and second primary tracks on opposite sides of the tape in the widthwise direction thereof; and alternately recording a first visual information signal corresponding to the audio signal in the first primary tracks and a second visual information signal corresponding to the audio signal in the second primary tracks in a single secondary track positioned in the center of the tape in the widthwise direction thereof, the first visual information signal being recorded in first information blocks in the secondary track and the second visual information signal being recorded in second information blocks in the secondary track in an alternating relation with the first information blocks such that only the first visual information signal is reproduced when reproducing the audio signal from the first primary tracks and only the second visual information signal is reproduced when reproducing the audio signal from the second primary tracks. The preset invention is also directed to apparatus for performing the above method.
摘要:
Novel synthetic polypeptide derivatives, i.e., novel calcitonin derivatives, having improved basic physiological activities of the corresponding natural calcitonins, i.e., the activity for lowering the blood level of calcium, the activity as an analgesic, as well as the activity for inhibiting the secretion of the gastric juice. Thus these synthetic calcitonins are effective as agents for curing hypercalcemia, analgetic agents, anti-ulcerative agents and the like.

A magnetic video recording apparatus for intermittent recording comprises a magnetic tape driving circuit (30), a video signal recording circuit (20), a control circuit (40) and a recording start instructing circuit (60). The magnetic tape driving circuit (30) makes a magnetic tape (1) travel at a predetermined speed while it is enabled. The video signal recording circuit (20) records a video signal (VS) in the magnetic tape (1) in a predetermined format. The recording start instructing circuit (60) provides intermittently a recording start signal (RS). The control circuit (40) enables the magnetic tape driving circuit (30) in response to the recording start signal (RS), enables the video signal recording circuit (20) for a predetermined period of time and then disables the magnetic tape driving circuit (30). A tape pattern thus recorded in the magnetic tape (1) does not differ from that in an ordinary video tape recorder. Accordingly, the above described magnetic tape (1) can be continuously reproduced by an ordinary video tape recorder.
