摘要：
Apparatus having corresponding methods and computer programs comprise a wireless receiver to receive a Very High Frequency (VHF) Omni-directional Radio Range (VOR) signal comprising a frequency-modulated (FM) component; an analog-to-digital converter to generate a digital signal based on the VOR signal, the digital signal comprising data representing the FM component; and a FM phase circuit comprising a correlator to generate a correlation peak based on the data representing the FM component and an ideal representation of the FM component, and a peak detector to determine a phase of the FM component based on the correlation peak.
