The primary and secondary of an LVDT (stroke ± 50 mm) are connected to 3 kHz sinusoidal source and ideal semiconductor diode bridge-based phase sensitive demodulator circuit. The core of the LVDT remains static at 15 mm above the ideal null position. The frequency of the voltage observed at the input of the low pass filter is
1
1 kHz
2
1.5 kHz
3
3 kHz
4
6 kHz
