Abstract: Provided is an intermediate-frequency analog-to-digital conversion device, including: a gain attenuation module, a gain amplification module, a filter and an analog-to-digital conversion module. The gain attenuation module is configured to perform attenuation processing on a received intermediate-frequency signal. The gain amplification module is connected to the gain attenuation module, and configured to perform amplification processing on a signal that is output from the gain attenuation module. The filter is a variable filter, connected to the gain amplification module, and configured to perform filter processing on a signal that is amplified by a gain amplifier. The analog-to-digital conversion module is connected to the filter, and configured to convert a signal that is filtered by the filter into a digital signal. The technical solution solves the technical problem in the related art and achieves the technical effect of improving the universality of the intermediate-frequency analog-to-digital conversion device.

Abstract: Provided are a phase detection method and apparatus for a clock signal, and a communication device. A clock signal of a clock to be detected is sampled according to sampling periods set by a sampling clock; a phase angle value corresponding to a sampled clock signal in a current sampling period is obtained according to a mapping relationship between sampled signals and phase angle values; a phase difference corresponding to the current sampling period is subtracted from the phase angle value to obtain an initial phase value of the clock to be detected in the current sampling period, wherein the phase difference is a phase difference between the clock to be detected and the sampling clock in the current sampling period; and after the sampling ends, a final phase value of the clock to be detected is obtained according to initial phase values obtained in respective sampling periods.
