  • Patent number: 7519491
    Abstract: A data processing method is provided to enable a calculation based signal analyzer, such as an FFT based spectrum analyzer, to produce results corresponding to a swept spectrum analyzer employing a video bandwidth (VBW) filter. Once a spectrum is produced the frequency axis is replace by a corresponding time axis, so that a time domain filter, such as a video bandwidth (VBW) filter can be applied. The filter characteristics are applied by performing an FFT to produce frequency domain data, multiplying by the frequency response to produce a filtered version, performing an inverse FFT and replacing the time axis with the original frequency axis to produce a filtered version of the display spectrum data.

Once a spectrum is produced the frequency axis is replace by a corresponding time axis, so that a time domain filter, such as a video bandwidth (VBW) filter can be applied. In a first example, the filter characteristics are applied by performing an FFT on display spectrum data, which has had its frequency axis replaced by a corresponding time axis, produce frequency domain data, multiplying by the frequency response to produce a filtered version, performing an inverse FFT and replacing the time axis with the original frequency axis to produce a filtered version of the display spectrum data.

  • Patent number: 5025311
    Abstract: A Y/C separating apparatus used in video tape recorders, etc., and capable of performing correct adaptive Y/C separation without increasing the circuit scale substantially. The process includes the steps of converting an analog video signal to a digital video signal, converting the relation between the digital video signal and a delayed version of the digital signal into a data signal, delaying this data signal, and analyzing the relationship between the signals inclusive of the delayed data signal. Thus it is possible to perform an accurate adaptive Y/C separation without increasing the memory capacity substantially.
