The major difference between digital and analog FPV (First-Person View) goggles lies in the way they transmit video signals from the drone to the goggles:

1 Video Quality:

Digital FPV Goggles: Provide much clearer and higher-resolution video with minimal interference, offering a more immersive and detailed experience. The image quality is closer to HD and often has fewer issues with static or noise.
Analog FPV Goggles: The video quality is generally lower, with more noticeable interference, static, and noise. The image may be grainy or less sharp, especially over longer distances.

2 Latency:

Digital FPV Goggles: Generally have slightly higher latency, which means there’s a small delay between the drone's camera capturing the image and it being displayed on the goggles. However, this latency is often minimal and not noticeable in most situations.
Analog FPV Goggles: Offer very low latency, making them preferable for fast-paced flying or racing where immediate feedback is crucial.

3 Signal Range and Penetration:

Digital FPV Goggles: Typically offer better signal range and penetration, meaning they maintain a stable connection over longer distances and in environments with obstacles.
Analog FPV Goggles: The signal can degrade more quickly over distance and through obstacles, leading to more frequent dropouts or interference.
