hello friends
i am trying to do LVDT signal conditioning using TMS320F2812 DSP controller (instead of analog approach using AD698/598). I reffered some ti application note. there it is mentioned that the LVDT primary excitation is done throgh the DSP processor itself through some PWM technique.
Is it possible to use the external oscillator for excitation of the the primary of the LVDT and do the synchronous demodulation inside the DSP processor?
please help friends, i am much confused
