    The invention provides a tire pressure detection signal receiving circuit, a system and a method. The method comprises steps: a synchronization module performs synchronization and filtering processing on a received coded baseband signal, and a configuration module outputs a preset Baud rate and a preset synchronization mode; a detection module detects the processed baseband signal based on the preset Baud rate, and outputs an effective signal and an actual Baud rate; a clock generation module receives the preset Baud rate or the actual Baud rate and outputs a Baud rate clock; a frame synchronization module receives the effective signal and the Baud rate clock, samples the effective signal, matches the sampled signal with a preset synchronization mode, and outputs a cache signal; a decoding module receives the cache signal and the Baud rate clock and decodes the cache signal; and a configuration module receives the decoded data and sends the decoded data to an application module. The tire pressure detection signal receiving circuit is realized by adopting a hardware circuit, so that the dependence on software is small, the requirement on frequency can be reduced, and the power consumption and the cost of the tire pressure detection signal receiving circuit can be further reduced.
