Number of Lines in Frame Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Lines in Frame = Horizontal Frequency/Number of Frames per Second
N_L = f_hzl/FPS
This formula uses 3 Variables

Variables Used

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.
Horizontal Frequency - (Measured in Hertz) - Horizontal Frequency usually expressed in kilohertz is the number of times per second that a raster-scan video system transmits or displays a complete horizontal line.
Number of Frames per Second - Number of frames per second is the total no. of frames in a second.

STEP 1: Convert Input(s) to Base Unit

Horizontal Frequency: 48 Hertz --> 48 Hertz No Conversion Required
Number of Frames per Second: 24 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_L = f_hzl/FPS --> 48/24

Evaluating ... ...

N_L = 2

STEP 3: Convert Result to Output's Unit

2 --> No Conversion Required

FINAL ANSWER

2 <-- Number of Lines in Frame

Number of Lines in Frame = Horizontal Frequency/Number of Frames per Second
N_L = f_hzl/FPS

How many lines does a frame in TV signal is scanned?

The NTSC TV standard uses an aspect ratio of 4:3 (ratio of picture width to height), and 525 scan lines per frame at 30 fps. Each frame has an odd field and an even field. So there are 525/2 = 262.5 lines per field. NTSC actually uses 29.97 fps.

How to Calculate Number of Lines in Frame?

Number of Lines in Frame calculator uses Number of Lines in Frame = Horizontal Frequency/Number of Frames per Second to calculate the Number of Lines in Frame, The Number of lines in Frame formula is defined as the total number of frames line present in the television. Number of Lines in Frame is denoted by N_L symbol.

How to calculate Number of Lines in Frame using this online calculator? To use this online calculator for Number of Lines in Frame, enter Horizontal Frequency (f_hzl) & Number of Frames per Second (FPS) and hit the calculate button.
