    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.

    摘要: 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.
