What action does a repeater take upon receiving a bit pattern at its input?

When a repeater receives a bit pattern at its input, its primary function is to regenerate the signal to ensure it can propagate over longer distances without degradation. The repeater takes the incoming signal and amplifies it, producing the same bit pattern at its output, but at a higher power level. This amplification helps to counteract the loss of signal strength that occurs as data travels through a medium, allowing for clear and reliable communication over extended distances.

In this context, repetitions of the same bit pattern ensure that the integrity of the data is maintained, which is critical for effective data transmission. The process of regenerating the signal at a higher power level allows the repeater to extend the reach of the original transmission, ensuring that subsequent receiving devices can accurately interpret the data without errors caused by weak signals.
