Abstract
A position sensor connected to first and second electric signal sources to output a first electric signal with a first frequency and a second electric signal with a second frequency. The position sensor includes: a primary coil generating a magnetic alternating field with the first frequency; a first and a second secondary coil, the first and second secondary coils each magnetically coupled to the primary coil by the position transmitter, and third and fourth electric signals induced in the first and second secondary coils respectively by the generated magnetic alternating field; a frequency converter converts the third and fourth electric signals into respective first and second intermediate frequency signals, the frequency converter connectable to the second electric signal source. A Goertzel filter bank demodulates the first intermediate frequency signal to obtain a first demodulated signal and demodulates the second intermediate frequency signal to obtain a second demodulated signal.
