Signal conditioning is essential for ensuring high-quality video output in arcade systems. The most common types of signal conditioning include:

1. RGB Signal Processing: Arcade games often use RGB (Red, Green, Blue) signals for vibrant colors. Conditioning involves amplifying and balancing these signals to prevent distortion.

2. Sync Separation: Composite sync signals (horizontal and vertical) are separated to synchronize the display properly, ensuring stable and flicker-free visuals.

3. Voltage Level Adjustment: Arcade PCBs may output non-standard voltage levels, so conditioning circuits adjust these to match CRT or modern display requirements.

4. Noise Filtering: Electrical interference can degrade video quality. Conditioning filters out noise to maintain a clean signal.

5. Impedance Matching: Proper impedance matching prevents signal reflections, ensuring sharp and accurate video output.

These techniques are crucial for preserving the authentic arcade experience while adapting to different display technologies.
