Enter the total number of horizontal lines displayed and the time (sec) into the Calculator. The calculator will evaluate the Horizontal Scan Rate. 

Horizontal Scan Rate Formula

HSR = HL / T

Variables:

  • HSR is the Horizontal Scan Rate (lines/sec)
  • HL is the total number of horizontal lines displayed
  • T is the time (sec)

To calculate the Horizontal Scan Rate, divide the total number of lines by the time.

How to Calculate Horizontal Scan Rate?

The following steps outline how to calculate the Horizontal Scan Rate.

  1. First, determine the total number of horizontal lines displayed. 
  2. Next, determine the time (sec). 
  3. Next, gather the formula from above = HSR = HL / T.
  4. Finally, calculate the Horizontal Scan Rate.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total number of horizontal lines displayed = 800

time (sec) = 5
