Which of the following methods is crucial for ensuring good signal integrity?

The selection of appropriate connectors is crucial for ensuring good signal integrity because connectors play a significant role in how well signals can be transmitted without degradation. Proper connectors must be matched to both the cable type and the device they are connecting. The design of the connectors can impact factors such as impedance matching, which is essential to minimize reflections and maintain a consistent signal.

Using connectors that are not suitable for the specific cable or application can lead to increased attenuation, interference, and potential loss of information. Quality connectors will also ensure secure connections, which reduces the risk of intermittent signals or complete signal loss due to poor contact.

While other factors like cable quality and physical handling (such as cable bends) are important, the connectors themselves directly affect how efficiently and reliably signals are passed between devices. Therefore, selecting the right connectors is a foundational step in maintaining signal integrity in an AV system.
