Whats the difference between a Redstone repeater and a Redstone comparator?

Answered by Antonio Sutton

The main difference between a Redstone repeater and a Redstone comparator lies in their functionality and the way they allow current to pass through. While both devices are used in Redstone circuits to control the flow of Redstone signals, they serve different purposes.

1. Purpose:
– Redstone Repeater: A repeater is primarily used to extend the reach of a Redstone signal. It receives a signal input from its back and repeats it at full strength from its front. This allows the signal to travel a longer distance without losing its strength.
– Redstone Comparator: On the other hand, a comparator is used to compare the strength of two Redstone signals. It has two inputs: one from the back and one from the side. It compares the strength of these two signals and produces an output based on the comparison.

2. Signal Delay:
– Redstone Repeater: One important feature of a repeater is that it introduces a small delay in the Redstone signal. This delay can be adjusted using the repeater’s settings. It can be useful in circuits where precise timing is required.
– Redstone Comparator: Unlike a repeater, a comparator does not introduce any delay in the signal. It provides an instant output based on the strength of the input signals.

3. Signal Amplification:
– Redstone Repeater: A repeater not only extends the reach of a Redstone signal but also amplifies it. The output signal from the front of the repeater is stronger than the input signal received from the back. This amplification can be useful in situations where a stronger signal is required to power certain Redstone components.
– Redstone Comparator: In contrast, a comparator does not amplify the signal. It simply compares the strength of the input signals and produces an output signal based on the result of the comparison.

4. Output Modes:
– Redstone Repeater: A repeater has only one output mode, which is to repeat the input signal at full strength. It does not have any other output options.
– Redstone Comparator: A comparator, however, has multiple output modes. It can be set to three different modes: compare mode, subtract mode, and non-subtract mode. Each mode determines how the comparator outputs a Redstone signal based on the strength of the input signals.

To summarize, while both Redstone repeaters and comparators control the flow of Redstone signals, their functionalities and purposes differ. A repeater extends and amplifies the signal while introducing a delay, whereas a comparator compares the strength of input signals and produces an output accordingly, without any delay or amplification. Understanding these differences allows players to utilize these Redstone components effectively in their circuits and creations.
