1. A communication method, wherein the method is applied to a consumable chip, the consumable chip is capable of being installed on a consumable, the consumable is capable of being detachably installed on an image-forming apparatus, and the image-forming apparatus includes an image-forming control unit, the method comprising:
receiving a first input signal and a second input signal which are determined based on first information to-be-transmitted and sent by the image-forming control unit through a first connection terminal and a second connection terminal, wherein the consumable chip includes a substrate disposed with the first connection terminal and the second connection terminal; the first connection terminal is connected to a first connection pin of the image-forming apparatus which is different from a power supply pin and a ground pin; and the second connection terminal is connected to a second connection pin on the image-forming apparatus which is different from the power supply pin and the ground pin;
demodulating the first input signal and the second input signal to obtain demodulated signals; and
determining the first information to-be-transmitted sent by the image-forming control unit according to the demodulated signals.
