VIDEO NOISE REDUCER

Japan Radio Corporation  

NJM2210

The NJM2210 operates automatically as noise reducer with low supply voltage to Pin 7 and signal enhancer with high

voltage to Pin 7.

Fig.7 shows output characteristics when applied high or low voltage to Pin 7. This system is adding and subtracting

form signals and so the output characteristic distortion comb type filter comes from phase difference of each system.The

NJM2210 phase difference is 2 degree at 4MHz. High dynamic range of video signal is reallized by high supply voltage.

Fig.8 shows vertical and horizontal enhance on display. Vertical enhance is signal treatment within 1H of horizontal

synchronous time. Horizontal enhance is signal treatment between each horizotal synchronous signal and Fig.9 shows

this.
