Number of Horizontal Lines Lost during Vertical Retrace Solution

STEP 0: Pre-Calculation Summary

Formula Used

Horizontal Lines Lost = Vertical Retrace Time/One Horizontal Time
L_h = VRT/T_h
This formula uses 3 Variables

Variables Used

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.
Vertical Retrace Time - (Measured in Second) - Vertical retrace time a measurement of time related to video displays.
One Horizontal Time - (Measured in Second) - One horizontal time is the number of times per second that a raster-scan video system transmits or displays a complete horizontal line.

STEP 1: Convert Input(s) to Base Unit

Vertical Retrace Time: 1400 Millisecond --> 1.4 Second (Check conversion here)
One Horizontal Time: 70 Millisecond --> 0.07 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_h = VRT/T_h --> 1.4/0.07

Evaluating ... ...

L_h = 20

STEP 3: Convert Result to Output's Unit

20 --> No Conversion Required

FINAL ANSWER

20 <-- Horizontal Lines Lost

(Calculation completed in 00.006 seconds)

Width of Rectangle Picture

Go Width of Rectangle Picture = Height of Rectangle Picture Frame*Aspect Ratio

Number of Lines in Frame

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

Number of Frames Per Sec

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

Height of Rectangle Picture Frame

Go Height of Rectangle Picture Frame = Width of Rectangle Picture/Aspect Ratio

Aspect Ratio

Go Aspect Ratio = Width of Rectangle Picture/Height of Rectangle Picture Frame

Horizontal Resolution

Go Horizontal Resolution = Video Bandwidth*(2*One Horizontal Line Scan)

Vertical Retrace Time

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

Number of Horizontal Lines Lost during Vertical Retrace

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

Kell Factor or Resolution Factor

Go Kell Factor = Horizontal Lines Lost/Number of Lines in Frame

Vertical Resolution (VR)

Go Vertical Resolution = Number of Lines in Frame*Kell Factor

Number of Horizontal Lines Lost during Vertical Retrace Formula

Horizontal Lines Lost = Vertical Retrace Time/One Horizontal Time
L_h = VRT/T_h

What are the horizontal lines?

A horizontal line is one that goes from left to right across the page. This is because horizontal lines are parallel to the horizon. This fact can help children to remember the meaning of horizontal lines. It comes from the word “horizon”, which refers to the visible line that separates the earth from the sky.
