Kell Factor or Resolution Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Kell Factor = Horizontal Lines Lost/Number of Lines in Frame
KF = L_h/N_L
This formula uses 3 Variables

Variables Used

Kell Factor - Kell Factor is a parameter used to limit the bandwidth of a sampled image signal in television engineering.
Horizontal Lines Lost - Horizontal lines lost is defined as the number of times per second that a raster-scan video system transmits or displays a complete horizontal line.
Number of Lines in Frame - Number of Lines in Frame refers to the total number of horizontal lines that make up a complete frame of a video signal.

STEP 1: Convert Input(s) to Base Unit

Horizontal Lines Lost: 20 --> No Conversion Required
Number of Lines in Frame: 2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

KF = L_h/N_L --> 20/2

Evaluating ... ...

KF = 10

STEP 3: Convert Result to Output's Unit

10 --> No Conversion Required

FINAL ANSWER

10 <-- Kell Factor

Number of Lines in Frame

LaTeX Go Number of Lines in Frame = Horizontal Frequency/Number of Frames per Second

Number of Frames Per Sec

LaTeX Go Number of Frames per Second = Horizontal Frequency/Number of Lines in Frame

Number of Horizontal Lines Lost during Vertical Retrace

LaTeX Go Horizontal Lines Lost = Vertical Retrace Time/One Horizontal Time

Vertical Retrace Time

LaTeX Go Vertical Retrace Time = Horizontal Lines Lost*One Horizontal Time

Why is scanning necessary in television system?

Scanning is the important process carried out in a television system inorder to obtain continuous frames and provides motion of picture. The scene is scanned both in the horizontal and vertical directions simultaneously in a rabid rate.

How to Calculate Kell Factor or Resolution Factor?

Kell Factor or Resolution Factor calculator uses Kell Factor = Horizontal Lines Lost/Number of Lines in Frame to calculate the Kell Factor, The Kell factor or resolution factor formula is defined as a parameter used to limit the bandwidth of a sampled image signal to avoid the appearance of beat frequency patterns when displaying the image in a discrete display device, usually taken to be 0.7. Kell Factor is denoted by KF symbol.

How to calculate Kell Factor or Resolution Factor using this online calculator? To use this online calculator for Kell Factor or Resolution Factor, enter Horizontal Lines Lost (L_h) & Number of Lines in Frame (N_L) and hit the calculate button. Here is how the Kell Factor or Resolution Factor calculation can be explained with given input values -> 10 = 20/2.

FAQ

What is Kell Factor or Resolution Factor?
