1. What is Horizontal Frequency?

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.

2. How Does the Calculator Work?

The calculator uses the Horizontal Frequency formula:

\[ Horizontal Frequency = Number of Lines in Frame \times Number of Frames per Second \]

Where:

Explanation: The formula calculates the horizontal frequency by multiplying the number of lines per frame by the number of frames displayed per second.

3. Importance of Horizontal Frequency Calculation

Details: Horizontal frequency is a crucial parameter in video display systems as it determines the scanning rate of horizontal lines and affects the overall image quality and stability of the display.

4. Using the Calculator

Tips: Enter the number of lines in frame and number of frames per second as positive integers. Both values must be greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for horizontal frequency?
A: Horizontal frequency typically ranges from 15 kHz to over 100 kHz depending on the display resolution and refresh rate.

Q2: How does horizontal frequency relate to vertical refresh rate?
A: Horizontal frequency is calculated by multiplying the number of horizontal lines by the vertical refresh rate (frames per second).

Q3: Why is horizontal frequency important in CRT displays?
A: In CRT displays, horizontal frequency determines the speed at which the electron beam scans across the screen horizontally, affecting image stability and resolution.

Q4: Can this calculator be used for modern LCD displays?
A: While the basic principle remains the same, modern LCD displays may have different timing requirements, but the fundamental calculation of horizontal frequency still applies.

Q5: What units are used for horizontal frequency?
A: Horizontal frequency is typically measured in kilohertz (kHz), which represents thousands of horizontal lines scanned per second.
