Hi, I was asked to figure this out at work and I need some help!
I have a LVDT (Linear Variable Differential Tranformer) that spits out sine waves at 2 KHz, and I want to sample those sine waves 20 times per cycle (sample rate = 40 KHz?). Eventually those sampled rms values will be used for calculating addition, subtraction, divisions and CRCs in the FPGA (A3PE3000). Also, there is a 1.5ms delay from the LVDT to the FPGA.
How do I implement the sampling in the FPGA? a demodulator?
Thanks
