What do the vertical bars on an adaptive equalizer display represent?

The vertical bars on an adaptive equalizer display indicate the amount of equalization being applied to the channel. Adaptive equalizers are designed to counteract distortions and variations in signal quality, allowing for optimized communication over varying conditions. The height or intensity of the vertical bars correlates directly to how much equalization is necessary at any given moment to maintain signal integrity. This visual representation is crucial for technicians to monitor and adjust the equalization levels as needed to ensure optimal performance, making it an essential feature for effective signal processing.
