PWM - Pulse Width Modulation

Pulse Width Modulation Audio, or PWM, is a sophisticated way to provide users with audio information about the targets found. This audio system uses changes in the pulse width of the audio signal to detail the characteristics of the metal found. Here is a more detailed explanation of how this feature works:

Principles of PWM Audio Function:

1. Proportional Response:

   • PWM Audio provides an audio response that is directly proportional to the characteristics of the detected target. This means that the intensity and tone of the sound varies depending on the size, depth and metal type of the target.
   • For example, larger and more superficial objects will have louder and brighter sound, while smaller or deeper objects will produce a weaker and less distinct tone.

2. Pulse Width:

   • With PWM Audio, the pulse width of the audio signal that is generated when the detector encounters a metal object is adjusted. The pulse width affects the characteristics of the sound, which helps users better understand what type of target has been detected.
   • Longer pulses can be used to indicate larger metal targets, while shorter pulses indicate smaller targets.

3. Sound Quality:

   • The quality and character of the sound generated by the PWM are highly defined, allowing users to gain more information about the nature of the target without having to look at the detector display. This allows users to focus more on the search and less on analyzing the data on the display.

Advantages of PWM Audio:

• Better Target Identification:

  • Users can better distinguish between valuable targets and scrap metal, resulting in more efficient searches and less unnecessary digging.

• Improved Experience:

  • Audio signals are intuitive and provide instant feedback, improving the overall user experience during a search.

• Search Efficiency:

  • Allows users to process target information quickly and efficiently, which is especially useful in busy or audio-intensive environments.

Thus, PWM Audio delivers sophisticated audio processing technology that greatly improves the detector's ability to inform the characteristics of the targets found.
