Abstract: Disclosed are a method and an apparatus for eliminating a glitch, and a state machine, which are used for improving the accuracy of data transmission. The method includes: acquiring a transmission instruction of to-be-transmitted data, the transmission instruction at least carry the data; when it is determined that a first slave state machine can transmit the data, transmitting the to-be-transmitted data to the first state according to the transmission instruction; transferring the data according to a preset transfer state; when it is determined that a clock cycle for transmitting the data reaches a preset clock cycle, transferring the to-be-transmitted data to a preset state; and when it is determined that a preset transmission time is reached, transmitting the data.

Abstract: Provided are an infrared protocol-based infrared code transmission circuit, a chip, a remote control device and an air conditioner. The infrared code transmission circuit includes: a carrier duration control module; a processing module that is configured to configure the carrier duration control module according to a stage type of an infrared code to be transmitted in an infrared protocol, so that the carrier duration control module generates an enabling signal; a carrier generation module that is provided to generate a PWM-type carrier signal according to the stage type of the infrared code to be transmitted in the infrared protocol, and carry out a logic operation on the PWM-type carrier signal and the enabling signal to generate and transmit the infrared code to be transmitted.
