Each component in the video reproduction chain (including cables) should have an upper frequency limit (-3dB point) higher than this value to avoid degrading the image . Exceeding the video bandwidth produces images look soft or smeared, or otherwise distorted.
Read moreWhat is the bandwidth of video signal?
The Bandwidth of video signals of decent quality is in the range of 4.2 MHZ .
Read moreHow is signal bandwidth calculated?
The bandwidth of a signal is defined as the difference between the upper and lower frequencies of a signal generated. As seen from the above representation, Bandwidth (B) of the signal is equal to the difference between the higher or upper-frequency (fH) and the lower frequency (fL) .
