What is the difference between one-hot and dummy encoding?

The three most popular encodings for FSM states are binary, Gray, and one-hot. Binary Encoding. Binary encoding is the straightforward method you may intuitively use when you assign values sequentially to your states. This way, you are using as few bits as possible to encode your states.
